TRANSMIT/RECEIVE SWITCH WITH ESD PROTECTION AND METHODS FOR USE THEREWITH

摘要

A transmit/receive (T/R) switch includes a first transistor circuit that couples a power amplifier of a RF transceiver to an antenna port in response to a transmit enable signal indicating a transmit state. A second transistor circuit couples a low noise amplifier input to a first ground in response to the transmit enable signal indicating the transmit state. An electrostatic discharge (ESD) circuit includes a first diode that is coupled in parallel to the second transistor circuit.
