6446-380 ABSTRACT A microwave transmitter/receiver apparatus includes a housing, a primary radiator and a transmit/receive multiplexer for multiplexing a transmit signal and a receive signal. A transmit filter and a receive filter are connected respectively to a trans- mit input and a receive input of the transmit/receive multiplexer. A transmit circuit is connected to the transmit filter for outputting the transmit signal by receiving a predetermined transmit intermediate frequency (IF) signal. A receive circuit is connected to the receive filter for outputting a predetermined IF signal by receiving the receive signal. The multiplexer, the transmit and the receive filters, the transmit and receive circuits are accommodated in the housing. The primary radiator may be mounted in an opening of the housing adapted for wave radiation. At least the multiplexer may be provided as a waveguide circuit in the housing. The apparatus may further comprise a support for supporting the housing rotatably about a wave radiation axis of the housing. The apparatus can be made small and the polarization angle of a primary reflector can be matched to the polarization plane of a polarized wave. P-1796
