This paper presents a novel VSWR-resilient power amplifier (PA) consisting of three amplifiers combined via a hybrid coupler. By switching the roles of the three amplifiers among main, auxiliary, shor...
This paper presents a novel filtering power amplifier with frequency and mode reconfigurability. The design employs a tunable filtering quadrature coupler as a post-matching power combiner, consisting...
A dual-input outphasing power amplifier (PA) is presented in this work. To overcome the gain limitations of conventional outphasing PAs, a gain-enhanced single-stage branch amplifier is used in which ...
This work presents a watt-level two-stage differential power amplifier (PA) implemented in a 130nm SiGe BiCMOS technology. The PA is designed to operate in the 10–15 GHz portion of the FR3 band for th...
This paper presents a broadband bidirectional front-end that eliminates the antenna-side switch to enhance performance and save area. A reused matching network integrates transmit/receive (T/R) switch...
The development of accurate digital twins for RF systems enables designers and system engineers to accelerate innovation while minimizing the risk of costly late-stage errors. Employing models at diff...
Designing robust mm-wave circuits has become increasingly challenging as modern applications demand high performance across wide operating conditions. Recent AI-driven methodologies have accelerated m...
Data-driven surrogate modeling can greatly accelerate microwave component design, but the high cost of full-wave simulations demands efficient data acquisition. Existing sampling strategies often gene...
We present an auxiliary–generator (AG)–based outer–tier methodology that links existing simplicial path–following algorithms to commercial harmonic–balance (HB) simulators for the efficient tracing of...
This paper presents a further research progress in optimization of pixelated electromagnetic structures for design of microwave planar structures. A hybrid Wilkinson power splitter is considered, whic...
