A transceiver having a transmit/receive switch. The transmit/receive switch includes: a common port adapted for coupling to an antenna element; a transmit port; a receive port and a matched port. The transceiver includes a second switch. The second switch has: a common port adapted for coupling to an input/output port through a gain/phase control unit; a transmit port; a receive port and a matched port. The transceiver includes a balanced amplifier. The balanced amplifier includes a pair of input ports. A first one of the pair of input ports is coupled to receive port of the transmit/receive switch, and a second one of the pair of input ports is coupled to the transmit port of the second switch. The balanced amplifier includes a pair of output ports. A first one of the pair of output ports is coupled to the transmit port of the transmit/receive switch and a second one of the pair of ports is coupled to the receive port of the second switch.
