Polarization control via electric field application allows for selective acoustic phase inversion (API) to cause signal reflection via destructive interference. A specialized implementation of the modified Butterworth-Van Dyke (mBVD) model is presented to describe the\u0000<sc>on</small>\u0000 and\u0000<sc>off</small>\u0000 states of the switch. The equivalent circuit can accurately predict ferroelectric stacked crystal filter (SCF) S-parameters under various poling configurations and is also valid for the design of API RF switches. An integrated proof-of-principle device is presented using paraelectric barium strontium titanate, Ba0.5Sr0.5TiO3 (BST), SCFs. The switch has SCF-type response in the\u0000<sc>on</small>\u0000 state with insertion loss (IL) of under 1.8 dB and a notched\u0000<sc>off</small>\u0000 state response with an isolation of over 37 dB. The first thickness extensional mode occurs at 1.6 GHz, and the total area is \u0000<inline-formula> <tex-math>$100times 200~mu $ </tex-math></inline-formula>\u0000m, including decoupling capacitor (\u0000<inline-formula> <tex-math>$100times 100~mu $ </tex-math></inline-formula>\u0000m) and electrical connections. Moreover, total active area consumes less than \u0000<inline-formula> <tex-math>$26times 52~mu $ </tex-math></inline-formula>\u0000m, suggesting future miniaturization. With the increasing inclusion of ferroelectric materials, such as BST and scandium-doped aluminum nitride (ScAlN) in the next-generation acoustic wave devices, this novel switch provides an avenue to eliminate interconnects between RF switches and microwave acoustic filters in RF front ends.","PeriodicalId":13272,"journal":{"name":"IEEE Transactions on Microwave Theory and Techniques","volume":"73 1","pages":"6-13"},"PeriodicalIF":4.1,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142938239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leveraging advanced multimaterial additive manufacturing, the design potential of 3-D meta-atoms can be unlocked. Compared to conventional 2.5-D or quasi-3-D FSSs that incorporate vias or microstrip lines, the proposed centrally loaded geometries facilitate in-depth topological optimization. The assembly of diverse fundamental FSS shapes introduces multiple poles and zeros, contributing to broad in-band transmission, extensive out-of-band rejections, and sharp transitions while still attaining simplicity when using equivalent circuit-transmission line modeling and associated qualitative design aids. The application-oriented FSSs are properly configured to fit the K-Ka spectra, where the ultrawideband FSS covers a fractional bandwidth of approximately 2:1, and the dual-band FSS offers two near-equal absolute bandwidths of 8 GHz. Both designs are inherently polarization insensitive due to unit-cell symmetry, and their robustness against oblique incidences has also been experimentally verified for both TE and TM modes.","PeriodicalId":13272,"journal":{"name":"IEEE Transactions on Microwave Theory and Techniques","volume":"73 1","pages":"75-86"},"PeriodicalIF":4.1,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10766902","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142938241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By revisiting the load-modulated balanced amplifier (LMBA) theory using an S-matrix-based signal-flow approach, a generalized theory for wideband LMBA operation is developed, taking into account the frequency-dependent nature of all components. In addition, by analyzing the signal-flow behavior of LMBA, a frequency-agnostic phase-alignment condition is identified as critical for ensuring intrinsic broadband load modulation. This unique design methodology enables, for the first time, the independent optimization of broadband balanced amplifier (BA, as the peaking) and control amplifier (CA, as the carrier), thus fundamentally addressing the longstanding limits imposed on the design of wideband load-modulated power amplifiers (PAs). To prove the proposed concept, an ultrawideband RF-input PD-LMBA is designed and developed using GaN technology covering the frequency range from 0.2 to 2 GHz. Experimental results demonstrate an efficiency of 51%–72% for peak output power and 44%–62% for 10-dB output power back-off (OBO), respectively.","PeriodicalId":13272,"journal":{"name":"IEEE Transactions on Microwave Theory and Techniques","volume":"73 1","pages":"206-220"},"PeriodicalIF":4.1,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142938230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
