Abstract :
A novel power amplifier adopting switch-linear hybrid scheme (SLH-FWPA) is introduced to accomplish flexible waveforms power amplification in a high bandwidth at high output power rating. The final output stage of SLH-FWPA is derived from linear power amplifier architecture to maintain excellent output quality and well dynamic performance; and meanwhile using tracking power supplies for the linear output stage to acquire total system efficiency above 80% generally. Theoretic analysis for SLH-FWPA is given and experimental results verify the implementation of SLH-FWPA.
