Traditionally, for extending impedance space, a reactive term is introduced into the current waveform of the continuous inverse class-F PA. In this paper, two reactive terms are introduced into the current and voltage waveforms simultaneously. The proposed method results in an expansive impedance space for designing broadband continuous inverse class-F PAs. For validating the proposed theory, a broadband PA working over 1.2\u20134.0[Formula: see text]GHz is designed and fabricated. Experimental results indicate that the fabricated broadband PA delivers a saturation power of 40.2\u201342.8[Formula: see text]dBm and a drain efficiency of 50.7\u201369%. <\/jats:p>","DOI":"10.1142\/s0218126621500158","type":"journal-article","created":{"date-parts":[[2020,7,18]],"date-time":"2020-07-18T03:44:17Z","timestamp":1595043857000},"page":"2150015","source":"Crossref","is-referenced-by-count":3,"title":["Extended Inverse Class-F Continuum for Designing Broadband Power Amplifier"],"prefix":"10.1142","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8520-5384","authenticated-orcid":false,"given":"Decheng","family":"Gan","sequence":"first","affiliation":[{"name":"School of Physics and Electronic Engineering, Yibin University, Yibin, Sichuan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8744-395X","authenticated-orcid":false,"given":"Weimin","family":"Shi","sequence":"additional","affiliation":[{"name":"Department of Electronic and Computer Engineering, The Hong Kong University of Science and Technology, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2020,7,18]]},"reference":[{"key":"S0218126621500158BIB001","doi-asserted-by":"publisher","DOI":"10.1142\/S0218126618300076"},{"key":"S0218126621500158BIB002","doi-asserted-by":"crossref","first-page":"38","DOI":"10.1109\/MWC.2017.1600360","volume":"24","author":"Huang X.","year":"2017","journal-title":"IEEE Wirel.
