Abstract
Doherty power amplifiers with a controllable capacitor are disclosed. In certain embodiments, a Doherty power amplifier includes a carrier amplifier that amplifies a first radio frequency (RF) input signal, a peaking amplifier that amplifies a second RF input signal, and a combiner having a first input coupled to an output of the carrier amplifier, a second input coupled to an output of the peaking amplifier, and an output that provides a combined RF output signal. The combiner includes an inverter for providing impedance inversion between the first input and the output of the combiner, and a first controllable capacitor and a first inductor in series and operable to provide harmonic termination to the output of the carrier amplifier. A capacitance of the first controllable capacitor is controllable to tune both the inverter and the harmonic termination of the carrier amplifier.
