ABSTRACT:
A programmable antenna interface for coupling an antenna to a transceiver having a receiver section and a transmitter section, includes a transformer that is adjustable in accordance with a control signal. A transmit/receive module couples the transformer to the receiver section in a receive mode and to the transmitter section in a transmit mode. The control signal controls the transformer to a first impedance in the transmit mode and controls the transformer to a second impedance in the receive mode.
