In this work a 10 W GaN based class-F amplifier at 1 GHz is presented. The presented amplifier uses load modulation principle to achieve high efficiency over 11 dB output dynamic range. The output matching network is an L matching network with a tunable inductor and a tunable capacitor. The tunable inductor is based on a λ/4 impedance inverter and a switchable capacitor bank. The tunable inductor...
In this work a 6 W GaN based class-F amplifier is presented. The presented amplifier uses an adaptive matching output network to achieve high efficiency over 8.5 dB output dynamic range. The output matching network is an L matching network with a tunable inductor and a tunable capacitor. The tunable inductor is based on a lambda/4 impedance inverter and a switchable capacitor bank. The tunable inductor...
