Abstract:
A circuit includes a first node configured to receive a radio frequency (“RF”) signal, a first electrostatic discharge (ESD) protection circuit coupled to a first voltage supply rail for an RF circuit and to a second node, and a second ESD protection circuit coupled to the second node and to a second voltage supply node for the RF circuit. An RF choke circuit is coupled to the second node and to a third node disposed between the first node and the RF circuit.
