| Title: | Novel realisation of a broadband high-efficiency continuous class-F power amplifier | Authors: | Tuffy, Neal; Zhu, Anding; Brazil, Thomas J. | Permanent link: | http://hdl.handle.net/10197/12078 | Date: | 11-Oct-2011 | Online since: | 2021-03-31T11:27:14Z | Abstract: | This work outlines the analysis and design procedure employed for the realisation of a broadband Continuous Class-F power amplifier. 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 https://ieeexplore.ieee.org/document/6102882/ |
