Measurements at limited operating points cannot adequately capture response variations over prescribed ranges of input power and control voltage or support repeated measurements across multiple parameter combinations. A parameter-configurable automated measurement method is proposed. Input power, Pin, amplitude control voltage, VA, and phase control voltage, VP, are defined as configurable variables, and a deterministic measurement sequence is generated from user-defined start values, step sizes, and maximum values. At each measurement point, after a preset delay following the control-state update, a vector network analyzer (VNA) simultaneously acquires magnitude and phase within the same measurement operation. The corresponding VNA-link power PVNA and output phase \u03c6out are recorded as a structured response dataset for reconstructing power- and phase-response curves during post-processing. The method is implemented using a vector network analyzer, directional coupler, power-detection module, and data-acquisition unit. Repeated measurements under identical parameter configurations assess response repeatability, while an auxiliary detector branch monitors measurement-chain status. Power-response deviations are generally less than 0.03 dB, with a maximum of \u223c0.07 dB, and phase deviations remain on the order of 1\u00b0. Validation using a single module indicates that the proposed method enables parameter-configurable and repeatable amplitude\u2013phase response characterization under the tested conditions.<\/jats:p>","DOI":"10.1063\/5.0340641","type":"journal-article","created":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T12:46:37Z","timestamp":1789562797000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["A parameter-configurable automated measurement method for amplitude\u2013phase response characterization of microwave power amplifier modules"],"prefix":"10.1063","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2694-6131","authenticated-orcid":false,"given":"Liang","family":"Zhu","sequence":"first","affiliation":[{"name":"Institute of Plasma Physics, Chinese Academy of Sciences , Hefei 230031,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8183-635X","authenticated-orcid":false,"given":"Wendong","family":"Ma","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics, Chinese Academy of Sciences , Hefei 230031,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1046-8278","authenticated-orcid":false,"given":"Lianmin","family":"Zhao","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics, Chinese Academy of Sciences , Hefei 230031,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4991-1377","authenticated-orcid":false,"given":"Chenbin","family":"Wu","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics, Chinese Academy of Sciences , Hefei 230031,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3658-8243","authenticated-orcid":false,"given":"Miaohui","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics, Chinese Academy of Sciences , Hefei 230031,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9154-4983","authenticated-orcid":false,"given":"Zege","family":"Wu","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics, Chinese Academy of Sciences , Hefei 230031,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheng","family":"Liu","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics, Chinese Academy of Sciences , Hefei 230031,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8357-6854","authenticated-orcid":false,"given":"Mao","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics, Chinese Academy of Sciences , Hefei 230031,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4290-7703","authenticated-orcid":false,"given":"Xiaojie","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics, Chinese Academy of Sciences , Hefei 230031,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,9,16]]},"reference":[{"key":"2026091608463065000_c1","volume-title":"Phased Array Antenna Handbook","year":"2005","edition":"2"},{"key":"2026091608463065000_c2","doi-asserted-by":"publisher","first-page":"114916","DOI":"10.1016\/j.fusengdes.2025.114916","article-title":"Design specifications for the ion cyclotron heating amplifier system in the Divertor Tokamak Test facility","volume":"215","year":"2025","journal-title":"Fusion Eng.
