The APD architecture design consists of a branch line coupler connected to a T\u2010junction and a single linearizing branch with a single PIN diode. The analytical equations for gain and phase conversions of the proposed APD structure are derived using even\u2010 and odd\u2010mode analysis. The design procedure of the proposed APD to compensate power amplifiers (PAs) for certain AM\/AM and AM\/PM is presented. Simulation and measurement results verify the performance of the proposed APD. The measurement results of the proposed APD achieve a 5.3\u2010dB conversion gain and 10\u00b0 phase compression centered at 1\u2009GHz with 9% fractional bandwidth. To our knowledge, this is the first matched reflective\u2010type APD that utilizes a single linearizing branch to simplify, compact, and reduce the power consumption of the APD structure. Furthermore, a 500\u2010W PA is linearized using the proposed APD. The measurements indicate that the APD shifts the 1\u2010dB compression point by 3.8\u2009dB, and the phase change is reduced to less than 1.8\u00b0, whereas the IM3 is improved by 12\u2009dB at 3\u2010dB output power backoff.<\/jats:p>","DOI":"10.1002\/cta.70239","type":"journal-article","created":{"date-parts":[[2025,12,4]],"date-time":"2025-12-04T02:36:17Z","timestamp":1764815777000},"page":"601-607","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Novel High\u2010Power Analog Predistortion Structure Based on a Single Linearizing Branch"],"prefix":"10.1002","volume":"54","author":[{"given":"Mohamed","family":"Talha","sequence":"first","affiliation":[{"name":"Radar Department Military Technical College  Cairo Egypt"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7089-4674","authenticated-orcid":false,"given":"Ahmed\u00a0M.","family":"Elelimy\u00a0Abounemra","sequence":"additional","affiliation":[{"name":"Electronic Engineering Department Military Technical College  Cairo Egypt"}]},{"given":"Fathy\u00a0Mohamed\u00a0Abdel","family":"Kader","sequence":"additional","affiliation":[{"name":"Radar Department Military Technical College  Cairo Egypt"}]},{"given":"Mohammad","family":"Darwish","sequence":"additional","affiliation":[{"name":"Radar Department Military Technical College  Cairo Egypt"}]}],"member":"311","published-online":{"date-parts":[[2025,12,3]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/MMM.2015.2498079"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/cta.2956"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/eStream50540.2020.9108866"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/cta.2445"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/22.643856"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.2528\/PIERC21021604"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1109\/MWSYM.2011.5972885"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1109\/TED.2018.2890696"},{"key":"e_1_2_7_10_1","first-page":"508","volume-title":"Conference of the 2nd International Conference on Computer Science and Electronics Engineering (ICCSEE 2013)","author":"Chen X.","year":"2013"},{"issue":"1","key":"e_1_2_7_11_1","first-page":"101","article-title":"A Novel Analog Predistortion Linearizer Based on a Schottky Diode for Communication Applications","volume":"10","author":"Karimzadeh Baee R.","year":"2022","journal-title":"Journal of Electrical and Computer Engineering Innovations (JECEI)"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1109\/ICMMT58241.2023.10276785"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1109\/ICET51757.2021.9451154"},{"volume-title":"Microwave Engineering","year":"2021","author":"Pozar D.
