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...
This paper introduces a mmWave antenna architecture that employs out-of-plane conductor geometry enabled by a scalable electrochemical additive manufacturing (ECAM) process. ECAM facilitates the fabri...
This work proves, for the first time, the feasibility of 3-D printing dual-circular polarization monolithic W-band waveguide feed components. A two-step approach is adopted. First, a test batch of com...
