摘要: A QAM transmitter is disclosed that may reduce the frequency of local clock signals and/or switching driver circuits when generating a output signal for transmission. The generate number PWM indicative in-phase (I) and quadrature (Q) components, then use one or more selected even-order harmonics to signal. Odd-order be suppressed by selectively combining signals, any remaining unwanted using filters.
