| Zusammenfassung: | A Class-F power amplifier includes a harmonic matching network topology comprised of circuit elements configured relative to an output network of the power amplifier. The harmonic matching network topology suppresses higher-order harmonics in such a power amplifier and includes coupled-line capacitors and open-stubs that introduce harmonic terminations in the output network, and quarter-wavelength transmission lines to match an overall network to a 50-ohm output load. The harmonic matching network topology enables the power amplifier to exhibit desired performance characteristics in specific frequency ranges for high-power applications. |
