|Title:||Class-J RF power amplifier with wideband harmonic suppression||Authors:||Tuffy, Neal; Zhu, Anding; Brazil, Thomas J.||Permanent link:||http://hdl.handle.net/10197/12079||Date:||10-Jun-2011||Online since:||2021-03-31T11:29:23Z||Abstract:||This work outlines a design approach used for achieving highly efficient power amplification over a wide bandwidth, given narrowband passive harmonic load-pull results at a single center frequency. Specific considerations have been given to harmonic suppression concerns which are addressed by appropriate choice of matching network topology. The method is justified by amplifier fabrication using a commercially available 10W GaN HEMT transistor and achieving an efficiency of at least 60% over a 15% bandwidth from 2.3-2.7GHz. Output power between 10-12W was delivered across the band, centered at 2.5GHz. Harmonic suppression of at least -41dBc and -39dBc was obtained across the second and third harmonic bands respectively, largely removing the dependency on post-filtering.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2011 IEEE||Keywords:||Class-J; Harmonic suppression; High efficiency; Power amplifier||DOI:||10.1109/MWSYM.2011.5972873||Other versions:||https://mtt.org/past-and-future-ims/||Language:||en||Status of Item:||Peer reviewed||Is part of:||2011 IEEE/MTT-S International Microwave Symposium - MTT 2011||Conference Details:||The 2011 IEEE MTT-S International Microwave Symposium, Baltimore, Maryland, United States of America, 5-10 June 2011||ISBN:||9781612847566||ISSN:||0149-645X||This item is made available under a Creative Commons License:||https://creativecommons.org/licenses/by-nc-nd/3.0/ie/|
