Abstract

This invention relates to transmit/receive switching in a RF transceiver. Transmit and receive circuits share a common impedance matching network, 20. The impedance matching network is located between the antenna 22 and a branching point 28, where the circuit divides into two branches. A power amplifier (PA) and a low noise amplifier (LNA) are connected to respective branches. A series-switch T2 is connected between the impedance matching circuit and an amplifying section T1 of the LNA. The series switch and the amplifying section of the LNA may each include a respective FET. Preferably, there is no series switch between the impedance matching network and the PA. A DC bias voltage may be provided to the transmitter or/and receiver through the matching circuit.
