Abstract (en)
[origin: EP0231422A2] The invention relates to a miniaturized microwave transmitter/receiver apparatus which allows the polarization angle of a primary reflector to be readily matched to the polarization plane of a polarized wave. The apparatus comprises a housing (100), a primary radiator (104), a transmit/receive multiplexer for multiplexing a transmit signal and a receive signal, a transmit filter and a receive filter, transmit means connected to the transmit filter for outputting the transmit signal by receiving a predetermined transmit intermediate frequency signal, and receive means connected to the receive filter for outputting a predetermined intermediate frequency signal, the multiplexer, the transmit and the receive filters, the transmit means and the receive means being accomodated in the housing (100).
