Patent ID: 8222960

Claim:
An RF power amplifier, comprising: an RF choke coil connected to a voltage terminal through which an operating voltage is applied, the RF choke coil being configured to supply the operating voltage and interrupt an RF signal; a power amplification circuit unit configured to receive the operating voltage through the RF choke coil, amplify an input signal inputted through an input terminal, and output an amplified input signal through an output terminal; and an electrostatic discharge (ESD) protection unit connected between a first connection node and a ground, and configured to bypass an ESD voltage from the first connection node to the ground, the first connection node being a node between the voltage terminal and the RF choke coil, wherein the ESD protection unit comprises: a first diode circuit unit provided between the first connection node and the ground and configured to be turned on by a positive ESD voltage; and a second diode circuit unit provided between the first connection node and the ground and configured to be turned on by a negative ESD voltage.
