Abstract
Certain aspects of the present disclosure are directed towards a transceiver. An example transceiver generally includes: a transmit amplifier with an output coupled to a node of the transceiver; a receive amplifier with an input coupled to the node of the transceiver; a transmit-receive switch (TRSW) transistor coupled between the node and a reference potential node; and one or more diodes coupled between the node and a gate of the TRSW transistor.
