A four-way triple-tank-based power combiner is introduced and theoretically analyzed in detail with the consideration of the undesired inductor in the third tank. The coupling coefficient and the uncoupling resonant frequencies of the tanks can be adjusted to compensate for the deterioration caused by the undesired inductor, achieving broadband and low-loss matching. The proposed PA operates over 4.4-6.4 GHz and exhibits a peak gain of 35.2 dB, a maximum saturated output power (Psat) of 30.5 dBm, and a peak power added efficiency (PAE) of 34.8% at 5.4 GHz.","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":"135104535","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}

Additionally, it proposes a novel complementary push-pull DC offset calibration method to calibrate the DC voltage of the lowpass filter with the common mode voltage. Compared to traditional methods, the proposed scheme effectively stabilize the quiescent operating point of the receiver. The experimental results show that the power consumption of the proposed filter is 0.019 mW, calibrated DC voltage is 1.65 V, and residual DC voltage is less than 1 mV.","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":"136373087","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}

In the proposed topology, two harmonic termination circuits are employed to shape the current waveform to half sine wave and voltage waveform to square wave by yielding short termination at even harmonics and open termination at odd harmonics. Compared with previous class-F voltage doubler rectifiers, the proposed rectifier achieves a higher RF-DC power conversion efficiency (PCE). To validate the proposed approach, a 2.45 GHz voltage doubler rectifier has been designed and implemented. The measurement results show that the peak RF-DC PCE is 76% with a 15.6 dBm input power range. In addition, the measured PCE is higher than 50% over the input power range from 2 to 18 dBm.","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":"135561367","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}
