The transmit signal is partially modulated by one of the digital constellation schemes, such as phase-shift keying. Extending a previous study, which investigated the general idea of the partial modulation at 4 GHz under AWGN scenarios, this letter analyzes the channel effect on the CaCSR communication performance and presents results from measurement at 79 GHz. For this purpose, the number of assigned communication symbols is compared with the channel length, the duration of the communication section, and the pause between the chirps, where the communication receiver comprises a direct architecture with a small fraction of the whole radar bandwidth. Finally, the performance of the proposed system is verified via simulation and measurement results, showing that it achieves superior communication performance compared with a reference method where only one modulation symbol is transmitted per chirp at the cost of negligible radar performance degradation.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"34 10","pages":"1214-1217"},"PeriodicalIF":0.0,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397432","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}

The standard continuous inverse class-GF is used as the core operating mode, and the relationship between phase shift and input/output impedances is constructed, thereby obtaining the available phase shift range corresponding to the expected rectification efficiency. It allows a variable range of phase shift, rather than a fixed 180°. This variable phase shift range greatly releases the design of the broadband matching, providing the possibility to expand the bandwidth of the rectifier. To verify the effectiveness of the proposed method, this work designs a broadband high-efficiency rectifier based on a GaN transistor. The test results show that within the operating frequency range of 1.8–2.8 GHz, a rectification efficiency of 60%–88% is achieved when the dc load is \u0000<inline-formula> <tex-math>$75Omega $ </tex-math></inline-formula>\u0000 and the input power is 40 dBm.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"34 10","pages":"1198-1201"},"PeriodicalIF":0.0,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397420","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}

To ensure that each transistor can achieve a proper active load impedance across a wide bandwidth during load modulation, a method for designing the impedance inverter with the optimal phase dispersion characteristic is proposed. For verification, a 24-to-28-GHz asymmetric GaN MMIC DPA was designed using a 150-nm GaN-HEMT process. The fabricated DPA achieved a saturated power range of 36.8–38.1 dBm, with a saturated power-added efficiency (PAE) of 29.7%–36.8%. The PAEs at 8- and 9-dB power back-offs (PBOs) ranged from 18.6% to 32% and 18.8% to 29.7%, respectively. After applying digital predistortion, the DPA achieved a high average PAE of 29% with good linearity when excited by a 400-MHz modulated signal.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"34 10","pages":"1174-1177"},"PeriodicalIF":0.0,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397444","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}

The wedges in this letter provide the auxiliary impedance matching and in-line cavity configuration in one structure. The auxiliary matching function is derived from the capacity to implement both shunt capacitive iris (CI) and RHW matching of WWI in a simultaneous manner. Due to the merits of design flexibility and structure compactness, a WR-3 band THz monolithic integrated frequency tripler based on the matching waveguide wedges is fabricated and then packaged in an extremely small flange-like cavity. The verified tripler exhibits a conversion efficiency of 2%–6.6% across the bandwidth of 200–325-GHz under 150 mW of pumped power.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"34 10","pages":"1186-1189"},"PeriodicalIF":0.0,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397447","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}
