Abstract
The efficiency performance of a Class E amplifier and its anti-parallel diode derivative are compared for two different operational modes, pulse width modulation (PWM) and load modulation. The effect of modulated signals is investigated. The anti-parallel diode proved effective in doubling the efficiency of the load modulation method, but this still did not surpass the efficiency of the traditional PWM mode of operation where an efficiency of 45% was indicated for a 8 dB peak to average Rayleigh enveloped signal
