Journal ArticleDOI
Performance of low-loss RF MEMS capacitive switches
TL;DR: In this paper, the construction and performance of metal membrane radio frequency MEMS switches at microwave and millimeter-wave frequencies was described. But the authors focused on the performance of the switches in terms of on-off capacitance ratio.
Journal ArticleDOI
Micromachined low-loss microwave switches
TL;DR: In this paper, the design and fabrication of a micromechanical capacitive membrane microwave switching device is described, which consists of a thin metallic membrane, which has two states, actuated or unactuated, depending on the applied bias.
Proceedings ArticleDOI
Lifetime characterization of capacitive RF MEMS switches

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.
