Abstract: An RF power amplifier circuit and input power limiter circuits are disclosed. A power detector generates a voltage output proportional to a power level of an input signal. There is a directional coupler with a first port connected to a transmit signal input, a second port connected to the input matching network, and a third port connected to the power detector. A first power amplifier stage with an input is connected to the input matching network and an output is connected to the transmit signal output.
