Continuous Class-F Power Amplifier Design by Using Multi-Harmonic Bilateral Pull

摘要

In this paper, multi-harmonic bilateral pull is used to design power amplifier (PA) fundamental and harmonics matching networks. By combining with continuous Class-F operation mode to realize high efficiency with broadband. And large signal dynamic device model is used in multi-harmonic bilateral pull to solve gain and efficiency decrease problem caused by the parasitic and nonlinear parameters. To verify the feasibility, CGH40010F device is used in the experimentation. The measured drain efficiency of the fabricated is between 64% and 75% from 1.5 to 2.5 GHz (50% bandwidth) with the gain is 9.9-11.8dB.
