Highly-miniaturized input-quasi-reflectionless bandstop filters (BSFs) are reported. They are based on a complementary RF diplexer design approach where the bandstop branch is formed by cascaded short...
This paper presents a passband flatness optimization framework for low quality factor (Q) filters using lossy coupling matrix (CM) synthesis. A lossy CM synthesis method is first proposed in the compl...
This paper presents a generalized interdigital bandpass filter that simultaneously achieves wideband flat group-delay (GD) and magnitude responses using tapped-feeding and unequal-length coupled lines...
Traditional acoustic wave (AW) ladder filters suffer from the rigid even allocation of extremely close transmission zeros (TZs) on both sides of the passband. Therefore, out-of-band (OoB) complex refl...
This work analyzes loss mechanisms in stacked switch-branch structures implemented in 28 nm FD-SOI CMOS on several substrates, from standard-resistivity silicon (10 Ωcm) to high-resistivity (HR &g...
This work presents the design and experimental demonstration of 25 GHz RF switches in 300 mm GaN-on-Si technology for mm-wave applications through systematic gate length optimization and multi-throw a...
This work demonstrates GaN-based non-volatile RF switches, implemented on a mature p-GaN/AlGaN/GaN-on-Si platform. The reconfigurable RF switch can be programmed to ON/OFF-state through efficient bipo...
This paper presents, for the first time, two-tone active load-pull measurements at 40 GHz applied to AlN/GaN HEMTs with and without a carbon-doped AlGaN back-barrier. The per-tone active load-pull arc...
Today, GaN power bars are the most common solution for achieving state-of-the-art output power and efficiency up to the C-band. Leading GaN suppliers worldwide continue to release new power bars, stea...
Concurrent dual-band power amplifiers (PAs) often experience significant efficiency degradation due to the strong baseband components generated under two-tone excitation. Conventional wisdom dictates ...
