A1101R09x – User’s Manual Page 5 of 33 Release Date 05/08/12 1. Overview The A1101R09A and A1101R09C are surface mount modules – each with an integrated crystal, internal voltage regulator, matching circuitry and filtering. The A1101R09A has an integral antenna, whereas the A1101R09C utilizes an external antenna through a U.FL connector (see Table 2). The modules operate in the US 902 – 928MHz ISM band and are ideal for achieving low power wireless connectivity without having to deal with extensive RF, antenna design and regulatory compliance, allowing quick time to market. The modules are 100% tested to provide consistent performance. The A1101R09A and A1101R09C have received regulatory approvals for modular devices in the United States (FCC) and Canada under Industry Canada (IC) Radio Standards Specification (RSS) RSS-210 and RSS-Gen. The modular approval allows the OEM or end user to place either an A1101R09A or an A1101R09C with an approved antenna inside a finished product without having to perform costly regulatory testing for an intentional radiator. Section 2.3 has information on the requirements for the end user/integrator must fulfill to use the modules without intentional radiator regulatory testing. The A1101R09A and A1101R09C are based on the CC1101 transceiver IC from Texas Instruments. All control lines for the transceiver are provided at module level for full control of its operation. Please see the CC1101 data sheet (www.ti.com) for how to control the modules. The A1101R09A measure 9x16x2.5mm and A1101R09C measures 9x12x2.5mm. The modules are footprint compatible with each other. 1.1. A1101R09A The A1101R09A has an integral antenna, providing high efficiency and near omni-directional radiation pattern. This approach offers the lowest system cost when the application allows collocation of radio and antenna. 1.2. A1101R09C The A1101R09C has a compact antenna connector that allows for locating the antenna away from the module due to form/function or in order to exit a metal enclosure, see Figure 7 – Figure 10 for more information on antenna location and enclosure considerations.

Simple certification labeling replaces testing. 1.4. Theory of Operation The A1101R09A and A1101R09C are for low power wireless applications in the US 902 – 928MHz ISM band. The devices can be used to implement a variety of networks, including; point to point, point to multipoint, peer to peer and mesh networks. The A1101R09A and A1101R09C both interface to an application microcontroller via an SPI bus. Physical and MAC layer functionality are accessed via the SPI bus through addressable registers as well as execution commands. Data received, or to be transmitted, are also accessed through the SPI bus and are implemented as a FIFO register (64 bytes each for Tx and Rx).
A1101R09x – User’s Manual Page 7 of 33 Release Date 05/08/12 To transmit, a frame of data is placed in the FIFO; this may include a destination address. A transmit command is given, which will transmit the data according to the initial setup of the registers. To receive data, a receive command is given, which enables the unit to “listen” for a transmission; when such a transmission occurs, it places the received frame in the FIFO. When neither transmit nor receive is required, the device can enter either an Idle mode, from which it can quickly re-enter receive, a transmit mode, or a low power sleep mode from which a crystal startup is required prior to transmit or receive operation. Below is a block diagram for each of the A1101R09A and A1101R09C modules.  Antenna o The antenna couples energy between the air and the AIR module. For applications where installations are done by an end user (non-professional), an omni-directional antenna pattern is desired such that the application will work equally well in any direction. Similarly for peer to peer or point to multipoint applications an omni-directional pattern is desired such that all nodes have a fair chance of communicating. The A1101R09A module has an integral antenna that is near omni-directional, whereas the A1101R09C has approved antenna options ranging from near omni-directional to shaped front/back patterns (useful for inline, professional installations). Note that the end radiation pattern depends not only on the antenna, but also on the ground plane, enclosure and installation environment.  Filtering o Filtering removes spurious signals to comply with regulatory intentional radiator requirements.  Matching o Matching provides the correct loading of the transmit amplifier to achieve the highest output power, as well as the correct loading for the receive LNA to achieve the best sensitivity.  Physical o The physical layer provides conversions between data, symbol and RF signal.  MAC o The MAC layer is part of the Logical Link Layer and provides frame handling, addressing and medium access services.  Microcontroller Interface o The microcontroller interface exposes registers and commands for the physical and MAC layers to a microcontroller.  Power Management o Power management ensures a stable supply for the internal functions, as well as providing means for a low power sleep mode (in which case, most of the transceiver is power off).

A1101R09x – User’s Manual Page 9 of 33 Release Date 05/08/12 Figure 3 Transceiver IC block diagram. 1.4.1. Typical Flow After initial setup of registers for desired behavior, the normal operation flow diagram is shown in Figure 4. In applications of infrequent data transmissions, the transceiver would be in “sleep” mode to save power. From there it would awaken and then enter “idle” mode. As part of the wake up process the crystal oscillator is started (~240μs) and the digital microcontroller interface is powered up. Before transmit or receive, the frequency synthesizer needs to be started (“FS_Wakeup”) and, having been powered off (or idle for a while), the control loop of the VCO/PLL needs to be calibrated (“calibrate”). A data frame is loaded into the transmit FIFO and the “TX” mode is entered. The transceiver will transmit the data and enter “idle” mode after completion. When transmit is complete “RX” mode is entered to wait for the acknowledge frame. Once a frame is received, the transceiver will again enter “idle” mode. If no acknowledge frame is received within a given timeout, the data frame would be re-transmitted. If the acknowledge frame indicates that the data was received, the next data frame will be transmitted. After the last data frame has been transmitted successfully, the transceiver will again be put in “sleep” mode.

Page 14 of 33 A1101R09x – User’s Manual Release Date 05/08/12 2.1.1.2. End User Manual The end user manual should include the following statement: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and radiates radio frequency energy, and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:  Reorient or relocate the receiving antenna.  Increase the separation between the equipment and receiver.  Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.  Consult the dealer or an experienced radio/TV technician for help. 2.1.1.3. RF Exposure All transmitters regulated by the FCC must comply with RF exposure requirements. OET Bulletin 65 “Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields” provides assistance in determining whether proposed or existing transmitting facilities, operations or devices comply with limits for human exposure to Radio Frequency (RF) fields adopted by the Federal Communications Commission (FCC). The bulletin offers guidelines and suggestions for evaluating compliance. If appropriate, compliance with exposure guidelines for mobile and unlicensed devices can be accomplished by the use of warning labels and by providing end users with information concerning minimum separation distances from transmitting structures and proper installation of antennas. The following statement must be included as a CAUTION statement in manuals and OEM products to alert end users of FCC RF Exposure compliance: To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operation at closer than this distance is not recommended. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. If the A1101R09A and A1101R09C module is used in a portable application (antenna is less than 20 cm from persons during operation), the end user is responsible for performing Specific Absorption Rate (SAR) testing in accordance with FCC rules 2.1091.
A1101R09x – User’s Manual Page 15 of 33 Release Date 05/08/12 2.1.2. Canada (Industry Canada, IC) The A1101R09A and A1101R09C modules have been certified for use in Canada under Industry Canada (IC) Radio Standards Specification (RSS) RSS-210 and RSS-Gen. From section 3.2 RSS-Gen, Issue 3, December 2010, Modular Approval for Category I Equipment or Category II Equipment: “Modular approval permits the installation of the same module in a host device or multiple host devices without the need to recertify the device. Equipment certification for a modular device may be sought for either Category I equipment or Category II equipment. Transmitters designed as modules for the installation in a host device may obtain equipment certification as a modular device provided that the applicable RSS is met and the following conditions in this section are met.” In section 7.1.2 Transmitter Antenna, it has been mentioned that the user manuals for transmitters shall display the following notice in a conspicuous location: Notice: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Avis: Sous la réglementation d'Industrie Canada, ce transmetteur radio ne peut fonctionner qu’en utilisant seulement une antenne d'un type et d’un maximum (ou moins) de gain approuvé pour l'émetteur par Industrie Canada. Pour réduire des potentielles interférences radio pour les autres utilisateurs, le type d'antenne et son gain doivent être choisis de sorte que la puissance isotrope rayonnée équivalente (PIRE) ne dépasse pas ce qui est nécessaire pour une communication réussie. 2.1.2.1. IC Labeling Requirements From section 3.2.1 RSS-Gen, Issue 3, December 2010, Labeling Requirements for the Host Device: The host device shall be properly labeled to identify the modules within the host device. The Industry Canada certification label of a module shall be clearly visible at all times when installed in the host device, otherwise the host device must be labeled to display the Industry Canada certification number of the module, preceded by the words “Contains transmitter module”, or the word “Contains”, or similar wording expressing the same meaning. From section 5.2, RSS-Gen, Issue 3, December 2010, Equipment Certification Numbers and Labels: Every unit of Category I radio apparatus certified for marketing and use in Canada shall bear a permanent label on which is indelibly displayed the model number and Industry Canada certification number of the equipment model (transmitter, receiver, or inseparable combination
Page 16 of 33 A1101R09x – User’s Manual Release Date 05/08/12 thereof). Each model shall be identified by a unique combination of a model number and a certification number, which are assigned as described below in this section. The label shall be securely affixed to a permanently attached part of the device, in a location where it is visible or easily accessible to the user, and shall not be readily detachable. The label shall be sufficiently durable to remain fully legible and intact on the device in all normal conditions of use throughout the device’s expected lifetime. These requirements may be met either by a separate label or nameplate permanently attached to the device or by permanently imprinting or impressing the label directly onto the device. The label text shall be legible without the aid of magnification, but is not required to be larger than 8-point font size. If the device is too small to meet this condition, the label information may be included in the user manual upon agreement with Industry Canada. Label: Contains IC: 8975A-A10040601 Notice: This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Avis: Cet appareil est conforme avec Industrie Canada RSS standard exempts de licence (s). Son fonctionnement est soumis aux deux conditions suivantes: (1) cet appareil ne peut pas provoquer d'interférences et (2) cet appareil doit accepter toute interférence, y compris les interférences qui peuvent causer un mauvais fonctionnement du dispositif. For more information, see: Industry Canada http://www.ic.gc.ca/. 2.1.2.2. RF Exposure All transmitters regulated by IC must comply with RF exposure limits as set forth in RSS-102, Issue 4, section 4, “Exposure Limits”. Furthermore RSS-102, Issue 4, Section 2 “Certification Requirements”, provides assistance in determining the specific requirements for compliance. If appropriate, compliance with exposure guidelines for mobile and unlicensed devices can be accomplished by the use of warning labels and by providing users with information concerning minimum separation distances from transmitting structures and proper installation of antennas. The following statement must be included as a CAUTION statement in manuals and OEM products to alert users of IC RF Exposure compliance: Notice: To satisfy IC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operation at closer than this distance is not recommended. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
A1101R09x – User’s Manual Page 17 of 33 Release Date 05/08/12 Avis: Pour répondre à la IC d'exposition pour les besoins de base et mobiles dispositifs de transmission de la station, sur une distance de séparation de 20 cm ou plus doit être maintenue entre l'antenne de cet appareil et les personnes en cours de fonctionnement. Pour assurer le respect, l'exploitation de plus près à cette distance n'est pas recommandée. L'antenne (s) utilisé pour cet émetteur ne doit pas être co-localisés ou fonctionner conjointement avec une autre antenne ou transmetteur. 2.2. Potential Interference Sources  Alarm systems o These typically use low duty cycles and are therefore easy to avoid using acknowledge/retransmit methods  Car alarms (internal motion sensors)  Video surveillance o These are typically operated on a fixed channel determined at installation time and can be avoided by using clear channel assessment. It may be useful to change the channel used by the video surveillance equipment also, if possible. 2.2.1. Time critical data If the user requires specific time critical data throughput that cannot tolerate the delays of potentially many re-transmissions, the user is encouraged to implement an environment-aware algorithm that periodically monitors/scans the frequency band and maintain a list of “best available” channels. 2.3. Approved Usage These radio modules can be used in a variety of physical layer configurations; the following restricts the use to maintain compliance with the above referenced certification bodies. The user is encouraged to use minimum power required to establish a link, thus minimizing interference. Changes or modifications to the module and/or operation outside the limits set forth below are prohibited and could void the user’s authority to operate the modules. Uses of these radio modules are limited to the following frequency ranges and modulation settings. Using the radio modules outside of these limitations are prohibited and could void the user’s authority to operate the modules. The user should use one of the register configurations listed below. Anaren provides register setting files for optimal performance and compliance for each of the data rates given in the following at www.anaren.com.
Page 18 of 33 A1101R09x – User’s Manual Release Date 05/08/12 2.3.1. USA & Canada Within the USA and Canada, the modules have been approved for use as digitally modulated transmitters, for which they must have a minimum occupied bandwidth (6dB bandwidth) of 500kHz. In addition, the spectral density may not exceed 8dBm/3kHz and the total output power including antenna gain may not exceed 1W. Table 3 shows configurations that are compliant with this use and the expected performance. Table 3 FCC Approved configurations with max. allowed output power In order to meet the band edge requirements, the center frequency of the operating channel has to be chosen between Fomin and Fomax. Also, the power levels provided in Table 3 are the max allowed power levels for each configuration, however, the user is encouraged to use minimum power required to establish a link in order to minimize interference. For available power levels from the module, please refer to Table 4. It is encouraged to use a medium access technique which should include addressing of individual transceiver nodes; and should include a combination of a clear channel assessment, transmit and detect, or a frequency hopping method. This ensures that the un-licensed band can be shared with other systems/applications.

This option is not generally recommended, but is a method to save PCB in an environmentally benign environment Figure 10 Mounting the module along an edge, with a ground plane cut-out. This option degrades range slightly.
Page 24 of 33 A1101R09x – User’s Manual Release Date 05/08/12 3.5. Power Supply Considerations Noise on the power supply line reduces the sensitivity of a receiver and modulates onto a transmitter’s signal, both of which causes a degradation of link quality and hence a reduction in range. The A1101R09A and A1101R09C radio modules each have an integral ferrite bead in the supply line from pin 18 (Vdd) and decoupling capacitance to reduce any noise on the incoming power supply line. This arrangement will eliminate most supply voltage noise. In particularly noisy environments (switching regulators, motor controls, etc.), it may be necessary to add additional noise reduction means. Pin 7 (Vdcoup1) is connected to the modules internal supply line after the ferrite bead and decoupling capacitors and can be used to probe the noise at module level. The noise level measured on pin 7 should not exceed 120mVpp when in transmit or receive mode; it may however exceed this value when setting up or accessing data to/from the FIFOs, while not actively transmitting or receiving. If the level measured is exceeding the above limit, steps should be taken to ensure maximum range, including:  Adding decoupling capacitance to pin 7 (Vdcoup1).  Adding additional filtering in the supply line. Adding an LDO in the supply line (the TPS731xx low Dropout Regulator from TI is recommended).

Page 28 of 33 A1101R09x – User’s Manual Release Date 05/08/12 4.3. Soldering AIR Modules may be mounted either manually (for prototyping or low volume production), or automatically for high-volume production. A no-clean tin/silver/copper (SAC) solder is recommended, however lead based no-clean pastes may also be used. CAUTION: AIR Modules are designed for no-clean fluxes only. DO NOT use water-based fluxes that require aqueous cleaning after solder. Spot cleaning with a flux remover and toothbrush may be performed with care. 4.3.1. Manual Mounting Procedure The recommended soldering method is reflow of a paste solder on a hot plate. This method works provided the bottom of the board where the AIR module is to be mounted is accessible, and there are no bottom-side components in the way. An aluminum or copper block may be placed on the hot plate surface to transfer heat to a localized area on the board where the AIR module is mounted - Set the hot plate to the reflow temperature solder manufacturer’s recommended - Apply solder paste to the pads on the board receiving the AIR module - Place the AIR module carefully onto the dispensed solder - Using tweezers or another holding device, carefully place board with AIR module onto the hot plate surface (or metal block) - Apply heat until reflow occurs, per solder paste manufacturer’s recommendations - Carefully remove the board and place on a heat-resistant surface to cool - Check assembly electrically to confirm there are no opens or shorts.
