The RTPS is composed of a 90\u00b0 hybrid coupler and two identical reflection loads. Lumped-distributed element transmission line is introduced in the 90\u00b0 hybrid coupler to reduce the chip size. Series inductor-capacitor (LC) resonators are used as the reflective loads and parallel inductors are deployed to reduce insertion loss variation. By cascading two-stage RTPS, 90\u00b0 phase shifting range and 10.5 dB insertion loss with 1 dB variations from 80 GHz to 90 GHz are achieved. An impressive 0.1 dB variation is obtained at 86 GHz.<\/jats:p>","DOI":"10.3390\/mi6030390","type":"journal-article","created":{"date-parts":[[2015,3,23]],"date-time":"2015-03-23T12:17:00Z","timestamp":1427113020000},"page":"390-395","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Compact W-Band Reflection-Type Phase Shifter with Extremely Low Insertion Loss Variation Using 0.13 \u00b5m  CMOS Technology"],"prefix":"10.3390","volume":"6","author":[{"given":"Xiao-Dong","family":"Deng","sequence":"first","affiliation":[{"name":"Ministerial Key Laboratory of JGMT, Nanjing University of Science and Technology, Nanjing 210094, China"},{"name":"Semiconductor Device Research Laboratory, Terahertz Research Centre, CAEP, Chengdu 611731, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yihu","family":"Li","sequence":"additional","affiliation":[{"name":"Semiconductor Device Research Laboratory, Terahertz Research Centre, CAEP, Chengdu 611731, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen","family":"Wu","sequence":"additional","affiliation":[{"name":"Ministerial Key Laboratory of JGMT, Nanjing University of Science and Technology, Nanjing 210094, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong-Zhong","family":"Xiong","sequence":"additional","affiliation":[{"name":"Semiconductor Device Research Laboratory, Terahertz Research Centre, CAEP, Chengdu 611731, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,3,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"45","DOI":"10.2528\/PIERL14051503","article-title":"Design of a Wideband Differential Phase Shifter with the Application of Genetic Algorithm","volume":"48","author":"Wang","year":"2014","journal-title":"Prog.
