  • Broadband power amplifier having high efficiency
    Patent number: 9881729
    Abstract: A wideband power amplifier module includes a plurality of switch mode amplifiers and a plurality of impedance amplifier modules. Each switch mode amplifier includes an input to receive an input signal, and an RF output to output an RF power signal. The switch mode amplifier includes at least one semiconductor switch formed from gallium nitride (GaN). Each impedance amplifier module includes an output electrically connected to the RF output of a respective switch mode amplifier. The impedance amplifier module is configured to inject at least one impedance control signal to each RF output.
    Type: Grant
