The design spaces of the class-F and inverse class-F in terms of input and output terminations are reviewed and compared, and the design choices relative to an implementation using a packaged device are described. Measurements show a saturated output power of 40 dBm, with corresponding efficiency and gain higher than 70% and 13 dB, respectively, over 1.4-2 GHz. The performance is well in line with the state of the art and is accurately predicted by simulations, proving the effectiveness of the design strategy.","PeriodicalId":207437,"journal":{"name":"2023 IEEE Topical Conference on RF/Microwave Power Amplifiers for Radio and Wireless Applications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121056939","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}

This ET configuration is specifically designed for wideband carrier aggregation (CA) signals that have 500 MHz corrected bandwidth and high peak to average ratio signals. Term selection is performed with Doubly Orthogonal Matching Pursuit (DOMP), an efficient sparse signal processing technique. This algorithm has been implemented for open loop and a batch mode closed loop operation. This model and these techniques reduce the number of inverse model terms significantly, using <40 terms of hundreds, while achieving improved spectral emissions, with computational efficiency, output signal fidelity and improved power efficiency. These algorithms are evaluated on a Gen 3, Xilinx ZCU208 RFSoC, achieving specification compliant performance, enabling future efficient real time closed loop operation.

First, the general sparse regression framework is presented. The StDOMP is formulated by applying the stagewise strategy to the DOMP algorithm, i.e., allowing the technique to select a block of components in each iteration without the need to perform one iteration per atom. The block selection approach allows to reduce the computational complexity up to a certain point where the performance is expected to be degraded. Experimental results highlight the behavior of the technique in the predistortion of a class AB power amplifier (PA) working in its nonlinear regime, concluding that the StDOMP is able to reduce runtime while still holding the performance level with respect to the DOMP.","PeriodicalId":207437,"journal":{"name":"2023 IEEE Topical Conference on RF/Microwave Power Amplifiers for Radio and Wireless Applications","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127074450","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}
