Abstract :
A 5-GHz high-efficiency feedback oscillator using a class-E amplifier is presented. The oscillator is designed at 5.0 GHz for maximum conversion efficiency using only quasilinear simulation techniques. A maximum conversion efficiency of 59% is measured with an output power of 300 mW. The oscillator can also be biased for a maximum power of 600 mW with a conversion efficiency of 48%.
