1. A microwave transmitter/receiver apparatus comprising:

  • a housing having a front shaft portion and a rear shaft portion, said housing having a central partition plate;

    a primary radiator adapted for wave radiation;

    a transmit/receiver multiplexer for multiplexing a transmit signal and a receive signal, said multiplexer having a transmit input and a receive input, at least the transmit/receive multiplexer being a waveguide circuit in the central partition plate of the housing;

    a transmit filter and a receive filter connected respectively to said transmit input and said receive input of said transmit/receive multiplexer;

    transmit means connected to said transmit filter for outputting the transmit signal responsive to receiving a predetermined transmit intermediate frequency (IF) signal;

    receive means connected to the receive filter for outputting a predetermined receive IF signal responsive to receiving the receive signal;

    means for accommodating the transmit/receive multiplexer, the transmit and the receive filters, the transmit means and the receive means in the housing;

    means for mounting the primary radiator in an opening in the housing; and

    support means coupled to said front and rear shaft portions for rotatably supporting the housing to turn about a wave radiation axis of the housing support means, thereby controlling the plane of a wave polarization.
