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...
In this paper we report record power added efficiency (PAE) on a vector load-pull system at 220 GHz, with minimal measurement error, of 31.3±0.8% for an Indium Phosphide (InP) Heterojunction Bipolar T...
We present an RF/mixed-signal technology based on 20-nm In0.8Ga0.2As HEMTs featuring backside gate and field plate architectures. It targets digital logic for monolithically integrated front-ends and ...
This paper presents a novel compact and highly-efficient GaN-based DC/DC converter module for 200 MHz switching frequency to supply point-of-loads (PoL) in data centers. By applying a distributed, int...
In response to the growing demand for wideband monolithic integrated front-ends, this work investigates passive double balanced mixers in a 35-nm gate-length InGaAs high-electron-mobility transistor (...
This paper presents an up-converter monolithic microwave integrated circuit (MMIC) based on GaN high-electron-mobility transistors (HEMTs) working over 100 GHz of radio frequency (RF) bandwidth up to ...
This paper presents a miniaturized, low-power, and low-phase-noise (PN) Ka-band voltage-controlled oscillator (VCO) tailored for FMCW radar applications. A complementary cross-coupled topology is empl...
This paper presents the design and experimental validation of a tri-functional K-band GaAs MMIC filtering amplifier isolator (FAI) that achieves a quasi-elliptic filtering response in the forward dire...
IF1-19: 8–27GHz Compact, Low-Power CMOS Active Power Divider Using CG-SF Topology and Inductor Array
This work presents a CMOS-based active power divider capable of covering most of FR3 band, with an operating frequency range from 8 to 27 GHz. Unlike conventional active power dividers that employ dis...
