Abstract
A radio communication transceiver includes a transformer, a switch, a power amplifier (AP), and a low noise amplifier (LNA). The transformer has a primary winding and a center-tap secondary winding, the primary winding has a first endpoint and a second endpoint, and the center-tap secondary winding has a first endpoint, a second endpoint, and a third endpoint. The switch has a gate, a drain, and a source, in which the gate receives a control signal (CS), the drain is connected to the second endpoint of the primary winding of the transformer through a coupling capacitor, and the source is grounded. The PA has at least one output terminal connected to the first endpoint and the second endpoint of the center-tap secondary winding of the transformer. The LNA has an input terminal connected to the second endpoint of the primary winding of the transformer.
