SSP-24303-D1

Rev. 1.0

Description:
Model SSP-24303-D1 is a K band ranging sensor module
based on FMCW radar principles. This sensor module isdesigned and manufactured for short range measurementsof a moving target's speed and direction. The sensor
module has a center frequency of 24.125 GHz and takes anominal bias of +5.0 VDC/250 mA. The frequency
modulation bandwidth of ±100 MHz minimum is realized
via a tuning voltage of 0 to +20 Volts. The sensor modules
are configured with a T/R diplexer, a dual channel (I/Q)
receiver and a transmitter/receiver oscillator in a die-casthousing. Various antennas can be integrated with themodule to form sensor heads for many system applications.
