This paper presents a hermetically packaged SP4T RF MEMS switch operating from DC to 40 GHz, designed with a grounded coplanar waveguide (CPWG) structure. Fabricated on an 8-inch fused silica wafer an...
This paper introduces a new class of Schiffman phase shifters, named as the Type G Schiffman phase shifter. For the first time, it is demonstrated that the bandwidth of Schiffman phase shifters can be...
In this paper, a 180° coupler achieving 18:1 operating frequency band is presented. The coupler is composed of three wideband multi-section Wilkinson power splitters connected by a wideband RF balun, ...
A compact 4-pole substrate integrated waveguide (SIW) bandpass filter exploiting the supercavity (SC) region is demonstrated. By cascading two pairs of high-index resonators (HIRs)-SIW resonators, str...
This paper presents a differential compact power divider realized with a single-inductor footprint in the back-end-of-line (BEOL) of IHP SG13S technology for D-band applications. Power dividers based ...
At mmWave, electromagnetic self-resonances induced by large capacitance and parasitic inductance increasingly distort the admittance of acoustic wave resonators and are usually treated as unwanted eff...
In this work, we demonstrate the first vanadium dioxide (VO₂) phase change material (PCM) RF single-pole, single-throw switches with >300 GHz bandwidth using optical excitation. PCM switches of...
This paper introduces a thin-film yttrium iron garnet (YIG) magnetostatic surface wave (MSSW) filter that achieves a low insertion loss of 2.2–5 dB, a flat and wide passband, and a continuous tuning r...
This paper presents a D-band transition architecture based on a three-substrate GaAs integrated passive device (IPD) platform, combining a dielectric-loaded WR-06 waveguide interface with two flip-chi...
Fixed-geometry phased arrays inherently suffer from frequency-aperture coupling: as frequency or scan angle changes, the electrical aperture and element spacing vary, leading to scan loss, beamwidth v...
