Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents quantitative evaluation of power efficiency decrese by not satisfying the zero current switching (ZCS) condition occurring in a bi-level quadrature-modulation (QM) envelope-pulse-width-modulation (EPWM) transmitter. Evaluation of power efficiency decrease is done by changing Q value of the series resonance circuit inserted in power amplifier (PA). As a result, the power efficiency decreases as the Q value increases. In addition, QM EPWM transmission system using quadrature polarized waves is proposed to satisfy ZCS condition for high efficiency. Simulation including digital signal processing with the QM EPWM and microwave circuit simulation with two class-D PAs shows that the proposed transmission system can demodulate both siguma and deruta component, and can improve power efficiency of the PAs.
