SYSTEM AND METHOD FOR AMPLIFYING AND COMBINING RADIOFREQUENCY POWER

Abstract:

System includes first and second amplifying circuits that are configured to receive input signals having a fundamental frequency. The system also includes first and second transmission lines that are configured to receive voltage and current waveforms from the first and second amplifying circuits, respectively. The system also includes a capacitively-compensated transmission line resonator (CC-TLR) that is configured to be electrically connected to a load having a load impedance. The CC-TLR is configured to receive and combine RF power from the first and second transmission lines. The CC-TLR has a compensation capacitance that causes the CC-TLR to present an open circuit at the fundamental frequency and present a short circuit at harmonic frequencies. Optionally, a characteristic impedance (Z.sub.0) of the first and second transmission lines and a load impedance (Z.sub.L) are unequal, and the first and second transmission lines cause a load impedance transformation.
