1. A transmit/receive switch, comprising:

  • a TX port for coupling to an RF transmit signal;

    a RX port for coupling to an RF receive signal;

    an antenna port for coupling to an antenna;

    an inductance coupled in series with said antenna port and said RX port; and

    a series combination of capacitance and a field effect transistor (FET) switch coupled in parallel across said inductance, wherein said FET switch having source, drain and gate terminals, the gate terminal operative to receive a control signal for controlling said FET switch.
