In the proposed method, the Pearson correlation coefficient is explored to solve the sensitivity analysis difficulty in accurately classifying the geometrical parameters into high-sensitivity parameters and low-sensitivity parameters. The relationship between high-sensitivity parameters and circuit responses is learned by the neural network as the first modeling step. Then, the effect of low-sensitivity parameters on the circuit response is restored in the second modeling step through transfer learning (TL), which leverages the knowledge gained from high-sensitivity parameters. Using the proposed sensitivity-driven stepwise modeling method allows us to achieve a much faster training convergence speed through effective knowledge transfer and reuse, consequently achieving similar accuracy in a shorter training time compared with existing methods using the same data. Two microwave modeling examples are used to illustrate the proposed method.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"35 1","pages":"19-22"},"PeriodicalIF":0.0,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142938488","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 PA adopts a three-stage design approach and a cascode structure to extend the supply voltage for higher gain and output power. The two-way power-combining technique is exploited to further improve the power delivered. By introducing an additional shunt capacitance, the insertion loss is reduced in the interstage matching before the power stage. This PA exploits the transformer coupling technique for interstage connection and compact layout techniques to make the PA suitable for millimeter-wave (mmW) applications. The PA provides 21.2 dBm of saturated output power (\u0000<inline-formula> <tex-math>$P_{mathrm {sat}}$ </tex-math></inline-formula>\u0000), 24.6 dB of transducer gain, and 20.6% of power-added efficiency (PAE) under a multiple supply voltage of 1.2 and 2.4 V and current consumption of 150 and 220 mA at 80 GHz, respectively. The PA occupies a core die size of \u0000<inline-formula> <tex-math>$800times 360~mu $ </tex-math></inline-formula>\u0000m. To the author’s knowledge, it is the first publication to improve the performance using shunt capacitance to improve the performance under cascode configuration.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"35 1","pages":"87-90"},"PeriodicalIF":0.0,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142938484","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 system simultaneously provides electric (GHz) and optical (super-resolution) imaging of live cells for broad applications in life sciences. It combines advantages offered by both open-ended coaxial probing and near-field scanning microwave microscopy (SMM) for accurate and quantitative local microwave measurements. The shielded tip minimizes unwanted absorption of microwaves by the biological media as compared to fringe fields of unshielded tips which we previously showed absorb over 90% of the signal and mask the true imaging signal. A proof-of-concept system built up with commercial off-the-shelf (COTS) components is demonstrated in the frequency range 0.01–6 GHz with micrometric spatial resolution, only limited by the coaxial probe geometry. Our work at the microscale lays the technological foundation for a true nano-radar in liquid cell imaging system that will come with further advances in nanofabrication technologies applied to coaxial probes and can be integrated with super-resolution optical microscopy, for an integrated full electromagnetic spectrum to probe biology at the nanoscale, from dc to lightwave.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"35 1","pages":"131-134"},"PeriodicalIF":0.0,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940860","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}
