Abstract
Summary form only given, as follows. A 1.95-GHz asymmetric multilevel outphasing (AMO) transmitter (TX) with class-E GaN PAs and discrete supply modulators is presented. A 4-level supply modulator is implemented for fast and efficient discrete envelope modulation with up to 28-V supply voltages. The AMO TX delivers 42.6-dBm peak output power with 62.5% PAE. For a 16-QAM signal at 36-dBm output power, the TX achieves 44.2/42.8/41.4% average system efficiency and 2.0/2.1/3.1% EVM for 10/20/40-MHz channel bandwidth, respectively.
