Abstract:
1. A wideband power amplifier module, comprising: a plurality of switch mode amplifiers, each switch mode amplifier including an input to receive an input signal and an RF output to output an RF power signal, and including at least one semiconductor switch formed from gallium nitride (GaN), and wherein each switch mode amplifier includes a coupled resonator transformer formed as a tapered cone winding having a center-tap terminal connected to a resonant capacitor that generates a resonant frequency output signal having a frequency ranging from 500 MHz to 6 GHz and is a Class F mode amplifier; and a plurality of impedance amplifier modules, each impedance amplifier module having an output electrically connected to the RF output of a respective switch mode amplifier, the impedance amplifier module configured to inject at least one impedance control signal to each RF output.
