ABSTRACT:
A transceiver module for use in a police traffic surveillance radar system is provided which is of a smaller size and of a lighter weight than those traditionally available. The transceiver module includes a front, open-ended housing having a cavity, a transceiver assembly disposed within the cavity of the housing, and a radome fixedly secured over the opened end of the housing so as to enclose and hermetically seal the transceiver assembly within the cavity of the housing. The transceiver assembly is formed of an antenna card/plate subassembly, a diode housing subassembly, an oscillator/choke housing subassembly, and a printed circuit board subassembly all operatively interconnected together so as to form a fully integrated structure. As a result, the transceiver can overcome the space restrictions due to the requirement of passenger-side air bags.
