The proposed system is able to provide a large number of reconfigurable multiple levels by arbitrarily controlling the output power of the two efficient power amplifiers. The novelty of the architecture relies in the efficient generation of the arbitrary multilevels. In fact, the system uses only one fixed supply voltage. An algorithm is developed to optimise the different symmetrical levels depending on the actual signal statistics in order to boost average system efficiency. A multilevel LINC transmitter system demonstrator was build to validate the proposed concept. Besides The system employs two identical hybrid power amplifiers designed using GaN HEMTs for a centre frequency of 2.28 GHz and output power of 40 dBm, the system employs only off-the-shelf components or measurement equipment. Measurement results on the demonstrator show that compared with a conventional LINC transmitter, average power efficiency of the proposed system can be improved from 28 % to 41 % for a WCDMA signal with a measured adjacent-channel-power ratio (ACPR) below -45 dBc. For a 10 MHz LTE signal efficiency is improved by nearly 24 percentage-points compared with a regular LINC system.","PeriodicalId":243164,"journal":{"name":"2012 7th European Microwave Integrated Circuit Conference","volume":"3 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127978906","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}

Conventional BB phase shifters use variable gain amplifiers (VGA), which have low linearity, and calibration is required for over 3-bit BB phase shifters. In this paper, we propose a novel BB phase shifter using fixed gain amplifiers (FGA) matrix with in/out-phase switches. Since FGA normally has higher linearity than VGA, it is possible to reduce overall power consumption to achieve same linearity. FGA has fixed reflection and transfer characteristic, so mismatch between phase shift states are reduced. By dividing phase shifter into smaller stages, the effects of process mismatches on very nearby transistors are small. So proposed structure has robustness against process mismatch. Fabricated 5-bit BB phase shifter using proposed method has a very low power consumption to achieve almost same linearity as other works and has a 3-dB bandwidth of 1.2 GHz, 1.5° of rms phase error, lower than 0.2 dB of rms gain error without calibration. For ambient temperature from -20 °C to 80°C, simulated rms phase error varied by only 0.2°, and did not vary with process mismatch.","PeriodicalId":243164,"journal":{"name":"2012 7th European Microwave Integrated Circuit Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131472689","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}
