Abstract
A system may include a radio frequency (RF) amplifier device that includes an input impedance matching network and first and second baseband decoupling circuits, which may remove intermodulation distortion products from signal energy input to the RF amplifier device at baseband frequencies. The input impedance matching network may act as a band-pass or low-pass filter. A gate bias voltage may be applied to the gate of a transistor in the RF amplifier device through one of the baseband decoupling circuits or, alternatively, at an input node of the RF amplifier device.
