Abstract
A circuit includes a power amplifier that includes a transformer having a primary winding and a secondary winding. The secondary winding has a first terminal and a second terminal. The circuit also includes a transmit/receive switch electrically connected between the first terminal of the secondary winding and electrical ground. The second terminal of the secondary winding is electrically connected to an antenna that transmits signals based on an output of the power amplifier and to an input of a second amplifier that is also connected to the antenna. The transmit/receive switch selectively switches between a closed position that connects the secondary winding to ground in a transmit mode and an open position that disconnects the secondary winding from ground in a receive mode.
