In addition, as larger non-contiguous chunks of the mm-Wave spectrum open up, dynamic frequency reconfiguration while ensuring high spectral and energy efficiency can become key towards optimal utilization of spectral resources. In this paper, we present a generalized asymmetrical multi-port combiner based network synthesis approach that enables both frequency and back-off reconfigurability in a mm-Wave power amplifier (PA) architecture to maintain high-efficiency operation with spectrally efficient codes across a wide frequency range. As a proof of concept, a silicon-based PA is presented which operates between 30–55 GHz with peak Psat of 23.7 dBm at 40 GHz and output collector efficiency (ηout) of 34.5 % and 22% at the 0 and −6 dB back-off respectively. The PA maintains ηout > 16% at −6 dB back-off across the range. Non-constant modulation is demonstrated with pulse shaping and with data rates upto 4 Gbps across the frequencies from 30–50 GHz.","PeriodicalId":349922,"journal":{"name":"2017 IEEE Radio Frequency Integrated Circuits Symposium (RFIC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125353757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
