  • Abstract
    Summary form only given, as follows. A VHF Doherty amplifier with independent drive-signal control is presented. An I-Q modulator/up-converter is used to produce the driving signals at a carrier frequency of 144-MHz. The amplifiers of the Doherty transmitter are designed using GaN FETs and lumped-element networks. The carrier amplifier operates in class-B with a drain efficiency of 63% while the peaking amplifier operates in class-C with an efficiency of 73%.
