Based on a simple modified band-pass output matching network, a novel second harmonic suppression method by utilizing the self-resonate characteristic of the on-chip capacitor is proposed, which can realize the harmonic suppression without any additional tuning structures. For verification, a 24-to-28-GHz GaN MMIC PA was designed using a 150-nm GaN on silicon carbide high electron mobility transistor process. The fabricated PA achieved a saturated power range of 32.5-34 dBm, with a corresponding power-added efficiency (PAE) of 37.5%-44.5%. The amplifier achieved good linearity when excited by a 400-MHz orthogonal frequency division multiplexing signal after applying digital predistortion.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135318369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It ensures the reference current accuracy while improving the performance of output voltage dynamic response.

A pipelined/SAR hybrid architecture with dual-channel sampling multiplying digital-to-analog converter (MDAC) and one shared flash sub-ADC is used exploiting a simple calibration.
