K-LC1 RADAR TRANSCEIVER

Description

K-LC1a is a 8 patch Doppler module with an asymmetrical beam for lowcost short distance
applications. Its typical applications are movement sensors in the security and automatic door
domain. In building automation this module may be an alternative for infrared PIR or AIR
systems 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 this
lowcost module even in ranging applications.
Powerful starterkits with signal conditioning and visualization is available from RFbeam.

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 sink
current.
Note 2: Transmit frequency stays within 24.075 to 24.175GHz over specified temperature range when the VCO pin is left open
Note 3: Theoretical value, given by design.

On this module the connector pin for the modulation input is not present. So this low-impedance
input is always not connected, what is the best case. So there will never be any 'unwanted'
modulation
