ABSTRACT:
A waveguide-to-microstrip transition module transmits captured electromagnetic energy between a waveguide and signal processing circuitry. The module is an assembly of a base which includes at least one waveguide, a circuit board having one side mounted to the base and the opposite side including at least one microstrip. The microstrip is simultaneously connected to signal processing circuitry and oriented with each waveguide. A backshort is associated with each microstrip. The module further includes a housing bonded to and containing, the base and circuit board. A cover is hermetically sealed to the housing to enclose the circuit board in the housing.
