Quantized tensor train (QTT) decomposition is applied to the finite-difference time-domain (FDTD) method to reduce the cost of spatial operations on structured grids. In a two-dimensional scattered-fi...
The Load Modulated Balanced Amplifier (LMBA) has found its space as a valid alternative to Doherty PAs. However, the flexibility of the LMBA action allows other modes of operation than efficiency enha...
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...
