Abstract
A radio communication transceiver achieving impedance matching when the transceiver operates in an output state and an input state respectively in a manner of switching a switch includes a transformer, a switch, a power amplifier (PA), and a low noise amplifier (LNA). The transformer has a primary winding including a first endpoint and a second endpoint and a secondary winding including a first endpoint and a second endpoint. The switch has a gate, a drain, and a source, wherein the gate receives a control signal, the drain is connected to the second endpoint of the primary winding, and the source is connected to the second endpoint of the secondary winding. The PA has an output terminal connected to the first endpoint of the primary winding of the transformer. The LNA has an input terminal connected to the second endpoint of the primary winding of the transformer.
