Abstract
A digital transmitter includes baseband interfaces to generate digital baseband signals with baseband frequencies, digital-upconverting stages to upconvert the baseband frequencies to first radio frequencies having a predetermined frequency range, a M-Band ΔΣM modulator to modulate the up-stage signals based on noise shaping and noise quantization processes, delay registers to align phases of the modulated up-stage signals, a noise canceler to generate noise canceling signals with a converted polarity, a Switch Mode Power Amplifier to amplify the phase aligned modulated up-stage signals up to a predetermined power level, a linear power amplifier to amplify the noise canceling signals up to the predetermined power level, a power combiner to combine to generate transmitting signals by combining the amplified phase aligned modulated up-stage signals and the amplified noise canceling signals, and an antenna to transmit the transmitting signals.
