Abstract

In this paper, a phase shift parameter is introduced to the current waveform of the series of continuous inverse modes (SCIMs) to generate complex fundamental and harmonic admittances. The extended design space based on this novel theory can offer alternative solutions for realizing broadband high-efficiency PAs. To verify the method mentioned above, a 0.9-2.1 GHz PA is designed and fabricated. Experimental results show the PA is able to achieve 63.3%-72.1% drain efficiency and 39.9-41.2 dBm saturated output power in the target band.
