ABSTRACT:
The radio frequency integrated circuit (RFIC) electrostatic discharge (ESD) circuit includes an integrated circuit pin and a radio frequency (RF) ESD circuit. The integrated circuit pin provides coupling to an antenna. The RF ESD circuit is operably coupled to the integrated circuit pin, wherein the RF ESD circuit provides ESD protection at the integrated circuit pin, provides coupling of inbound RF signals from the antenna to low noise amplifier, and provides coupling of outbound RF signals from a power amplifier to the antenna.
