W-Band Single Channel, Doppler Sensor Module

SSM-94313-S1 is a W band Doppler sensor module that is designed and manufactured for medium range measurements of a moving target's speed. The sensor module has an operating frequency of 94 GHz and takes a nominal bias of +4.5 VDC/750 mA. The sensor module is configured with a mechanically tuned oscillator, an isolator, a directional coupler, a circulator, a balanced mixer, and an oscillator voltage regulator. The directional coupler is used to sample the LO power to pump the mixer, and the circulator is used as a TX/RX diplexer. Various antennas can be integrated with the module to form sensor heads for many system applications.
