We present a 400 W class-E amplifier for industrial applications. The transistor is the International Rectifier IRFP450LC power MOSFET. The amplifier operates at 13.56 MHz and uses a drive level of 12 W to attain a drain efficiency of 86% and an overall efficiency of 84%. All harmonics are more than 40 dB below the carrier.
