“…In addition, the QM architecture is suitable for integration in a digital LSI because it does not include a complex phase modulator. Moreover, in principle it has superior quantum noise performance to a polarmodulation EPWM architecture [1], [3], [7], [9] which has nonlinearity in conversion from quadrature to polar coordinates [5].…”

We previously proposed a bilevel quadrature-modulation (QM) envelope-pulse-width-modulation (EPWM) transmitter using half a side of a trilevel EPWM architecture. However, the optimum relationship between the  modulation (DSM) sampling frequency (f s ), the interleaving frequency (f i ) and the carrier frequency (f c ) for a bilevel QM EPWM transmitter has not been investigated. This paper presents this optimum relationship, with the error vector magnitude (EVM) and the coding efficiency (CE) as figures of merit (FOMs).

This paper presents a bi-level quadraturemodulation (QM) low-pass (LP) envelope-pulse-widthmodulation (EPWM) transmitter using a half side of tri-level EPWM. Simulation including digital signal processing with the QM LP-EPWM and microwave circuit simulation with a class-D power amplifier (PA) using n-MOSFETs shows an excellent error vector magnitude (EVM) of 36 dB at 1 GHz. The transmitter with a class-D PA for bi-level EPWM signal shows much better EVM performance than the one for trilevel signal.Index Terms -transmitterpower amplifierclass-D envelope pulse-width modulationquadrature modulation, error vector magnitudepower-added efficiency
