Abstract:
A multi-stage RF power amplifier including passive circuitry for frequency spectrum control. In one example, a multi-stage RF power amplifier includes a first RF power transistor, a second RF power transistor, and a passive combination bandpass filter and impedance matching network coupled between the first RF power transistor and the second RF power transistor.
