V-band 2-b and 4-b low-loss and low-voltage distributed MEMS digital phase shifter using metal-air-metal capacitors
Hong-Teuk Kim,Jae-Hyoung Park,Sanghyo Lee,Seong-Ho Kim,Jung-Mu Kim,Yong-Kweon Kim,Youngwoo Kwon +6 more
TL;DR: In this article, a low-loss digital distributed phase shifters using micromachined capacitive shunt switches for V-band applications was developed using high-Q metal-air-metal capacitors in series with the microelectromechanical system (MEMS) shunt capacitive switches to minimize the dielectric loss.
Journal ArticleDOI
Low-loss and compact V-band MEMS-based analog tunable bandpass filters
TL;DR: In this paper, the two-pole filters were designed using the lumped-elements topology with metal-air-metal (MAM) bridge-type capacitors as tuning elements.
Journal ArticleDOI
Analysis and Design of Millimeter-Wave Power Amplifier Using Stacked-FET Structure
Young-Min Kim,Youngwoo Kwon +1 more
TL;DR: In this paper, a new analysis methodology for millimeter-wave stacked-FET power amplifier design is proposed with a focus on the output power improvement by adjusting the complex load-admittance of each stacked-transistor.
Journal ArticleDOI
Low-loss analog and digital micromachined impedance tuners at the Ka-band
TL;DR: In this article, the authors presented new types of analog and digital micromachined impedance tuners, where the short-circuited shunt stubs are loaded with microelectromechanical system (MEMS) capacitive switches.
Journal ArticleDOI
A V-band micromachined 2-D beam-steering antenna driven by magnetic force with polymer-based hinges
Chang-Wook Baek,Seunghyun Song,Jae-Hyoung Park,Sanghyo Lee,Jung-Mu Kim,Wooyeol Choi,Changyul Cheon,Yong-Kweon Kim,Youngwoo Kwon +8 more
TL;DR: In this paper, a two-dimensional mechanical beam-steering antenna was designed and fabricated on a single high-resistivity silicon substrate using microelectromechanical systems technologies, and a polymer-based hinge structure was used to increase the maximum scanning angle to as much as 40/spl deg/
