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":"106 1","pages":"0"},"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}

Diplexer consists of D-CRLH filters which include mixed coupling. The electromagnetic interaction is canceled out in the filter, generating two transmission zeros and giving the filter good stopband suppression. Diplexer utilizes a T-junction to make filters work in parallel. Each channel filter can be individually controlled. To validate the proposal, a diplexer operating at 1.88 GHz and 2.64GHz with fractional bandwidth (FBW) of 14.6% and 19.1% is designed and fabricated. A good agreement is perceived between measured and simulated.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135505127","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":"110 1","pages":"0"},"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}
