Charles L. Goldsmith,John C. Ehmke,A. Malczewski,Brandon W. Pillans,S. Eshelman,Zhimin Yao,J. Brank,M. Eberly +7 more
TL;DR: In this paper, the first experimental characterization of dielectric charging within capacitive RF MEMS switches has been demonstrated and their lifetimes were measured using a dual-pulse waveform with 30 to 65 V of actuation voltage.
Journal ArticleDOI
X-band RF MEMS phase shifters for phased array applications
TL;DR: In this paper, a low-loss radio frequency (RF) microelectromechanical (MEMS) 4-bit X-band monolithic phase shifter is presented.
Journal ArticleDOI
RF MEMS‐based tunable filters
TL;DR: In this paper, the basic operation of Raytheon's RF MEMS capacitive membrane switch is described, and an overview of the technique used to integrate the switch into a variable capacitor structure with sixteen capacitance states is provided.
Journal ArticleDOI
Reconfigurable double-stub tuners using MEMS switches for intelligent RF front-ends
TL;DR: In this article, a planar dynamically reconfigurable double-stub tuners that utilize electrostatically activated microelectromechanical system (MEMS) switches are presented. But their performance is limited by the range of loads that need to be matched.
Journal ArticleDOI
RF MEMs variable capacitors for tunable filters
TL;DR: In this article, an RF MEMs microelectromechanical system variable capacitor has been demonstrated with a 22:1 tuning range, tuning from 1.5 to 33.2 pF of capacitance.
