Abstract: A major drawback of digital transmitters (DTX) is the absence of a reconstruction filter after digital-to-analog conversion which causes the baseband quantization noise to get upconverted to radio frequency and amplified at the output of… read more here.

DOI: 10.1109/tmtt.2018.2808946
Abstract: This paper presents a novel multilevel radio frequency (RF) pulsewidth modulation (PWM) method for all-digital transmitters (ADTx) that actively eliminates the selected harmonics of RF-PWM. Compared with existing multilevel RF-PWM techniques, this method uses several… read more here.
