Abstract: A transceiver allowing transmission of a co-polar transmit signal and simultaneous reception of co-polar receive and cross-polar receive signals. An integrated orthogonal mode transducer and diplexer module containing a plurality of filters between a feed port, co-polar transmission port, co-polar reception port and cross-polar reception port is mounted within the transceiver housing with the feed port aligned with or forming the feed flange of the transceiver. A transmitter printed circuit board is aligned with the transmission waveguide port and a receiver printed circuit board is aligned with the co-polar reception and cross-polar reception ports of the integrated orthomode transducer and diplexer module.

Abstract: An LNB for simultaneous reception of circular and linear polarization radio frequency signals, having a circular waveguide coupled to a waveguide to microstrip turnstile transition. The microstrip outputs coupled to a multi-layer printed circuit board having symmetrical signal paths on separate layers. Each symmetrical signal path including a first combiner coupled to a low noise amplifier that is coupled to a splitter. A first output of each of the splitters having a linear polarization and a second output of each of the splitters coupled to a branch line combiner having two outputs, each of the two outputs having opposite hands of circular polarization.
