High-power, high-efficiency power amplifier reference design in III-V wide bandgap gallium nitride technology using nonlinear vector network analyzer and X-parameters

摘要

This paper presents a complete power amplifier design using new Nonlinear Vector Network Analyzer (NVNA) and X-parameter technologies. A high-power, pulsed Continuous Wave (CW) NVNA setup is presented and harmonic tuning capabilities of the measured X-parameter model is demonstrated using the same setup. From fundamental and harmonic impedance tuning, input and output power amplifier matching networks are synthesized and first-pass design success is confirmed by measurements of the fabricated power amplifier.
