BI-DIRECTIONAL AMPLIFIER WITH ELECTROSTATIC DISCHARGE PROTECTION

Abstract:

A transceiver circuit that includes a receiver and transmitter circuits may send and receive data signals using an antenna. The transceiver circuit may be coupled to the antenna and other circuits using multiple impedance matching networks configured to match input and output impedance values of the receiver and transmitter circuits to the antenna and other circuits. The impedance matching networks may selectively couple and decouple different ports of the receiver and transmitter circuits to other circuit nodes based on whether the transceiver is operating in transmit or receive mode.
