DescriptionK-LC1a is a 8 patch Doppler module with an asymmetrical beam for lowcost short distanceapplications. Its typical applications are movement sensors in the security and automatic doordomain. In building automation this module may be an alternative for infrared PIR or AIRsystems thanks to its outstanding performance/cost ratio.The module is extremely small and lightweight.With its IF bandwidth from DC to 50MHz it opens many new applications.FSK is possible thanks to the unique RFbeam oscillator design. This allows to use thislowcost module even in ranging applications.Powerful starterkits with signal conditioning and visualization is available from RFbeam.Find more informations at www.rfbeam.ch.Characteristics
Note 1: The VCP input has an internal voltage source with approx. 0.9 VDC. For driving this pin it is necessary to source and sinkcurrent.Note 2: Transmit frequency stays within 24.075 to 24.175GHz over specified temperature range when the VCO pin is left openNote 3: Theoretical value, given by design.On this module the connector pin for the modulation input is not present. So this low-impedanceinput is always not connected, what is the best case. So there will never be any 'unwanted'modulationAntenna System DiagramThis diagram shows module sensitivity in both azimuth and elevation directions. It incorporatesthe transmitter and receiver antenna characteristics.
FM CharacteristicsVCO Voltage generates an output signal even without an object in range because of the finiteisolation between transmitter and receiver path. This effect is called self-mixing and leads to aDC signal that depends on the carrier frequency / the VCO voltage.
ASSEMBLY INFORMATIONFeaturesThe radar module is mounted on a card reader pcb board and locked by a plastic support clip.Assembly DiagramStep 1: Place the plastic support on the Card reader board PCB.Step 2: Insert the radar module into base board radar connector.Radar ModulePlastic support clipBase board
Step 3: Close the support clip lockerStep 4: Place the card reader with radar inside your Port deviceFor example:
NOTE: The marking label oft he host appliance of the present radar module mustcontains the following inscription:“Contains FCC ID: XFIPORTRADARVER1”Application NotesSensitivity and Maximum RangeThe values indicated here are intended to give you a 'feeling' of the attainable detection rangewith this module. It is not possible to define an exact RCS (radar cross section) value of realobjects because reflectivity depends on many parameters.Please note, that range values also highly depend on the performance of signal processing,environment conditions (i.e. rain, fog), housing of the module and other factors.For simple detection purposes (security applications e.g.) without the need of speedmeasurements, range may be enhanced by further reducing the IF bandwidth. With 250Hzbandwidth and a simple comparator, we get already a 25m detection range.FCC in formations:This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:(1) This device may not cause harmful interference, and(2) this device must accept any interference received, including interference that may cause undesiredoperation.Changes or modifications not expressly approved by the manufacturer could void the user’sauthority to operate the equipmentThis equipment has been tested and found to comply with the limits for a Class B digital device, pursuantto part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmfulinterference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interferenceto radio communications. However, there is no guarantee that interference will not occur in a particularinstallation. If this equipment does cause harmful interference to radio or television reception, which can bedetermined by turning the equipment off and on, the user is encouraged to try to correct the interferenceby 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.FCC ID : XFIPORTRADARVER1
