Abstract
An integrated OMT/filter assembly is small, low cost and not easily susceptible to mechanical or environmental damage. The integrated OMT/filter assembly has a body formed at least in part of conductive material, the body including a first port for receiving a transmit signal, a second port for feeding the transmit signal to an antenna and for receiving a receive signal, and a third port for receiving the receive signal. A first waveguide segment joins the first and second ports, and a second waveguide segment joins second and third ports, the first and second waveguide segments having a portion in common. A filter element is disposed within at least one of the first and second waveguide segments.
