A radio frequency (RF) amplifier configured to operate at a fundamental frequency (f0) includes a transistor with a transistor output, an output matching network coupled to the transistor output, and a reflection absorption circuit. The output matching network includes an output path device connected between the transistor output and an output of the RF amplifier. The reflection absorption circuit is coupled between the transistor output and the output path device, and is configured to absorb reflected signal energy from the output path device.
