Waveform analysis is used in determining the most sensitive parameters for maintaining high efficiency over a desired bandwidth. A design methodology is then employed for control of the dominant parameters over the band of interest, while preserving maximum fundamental output power. By using a commercially available GaN Cree 10W HEMT transistor, an amplifier was fabricated which is operational over a 20% bandwidth. Greater than 11.4W of output power is found with efficiencies between 65-76% measured over the band from 2.152.65GHz. An average drain efficiency of 70.5% and PAE of 65% is obtained with a corresponding average output power of 13.5W.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2011 EuMA||Keywords:||Power Amplifier; Class-F; Broadband; High efficiency; GHZ||Other versions:||http://www.eumweek.com/2011/EuMIC.asp?id=c
