What are the applications of RF MEMS?

RF MEMS applications include phased arrays and reconfigurable apertures for defense and telecommunication systems, switching networks for satellite communications, and single-pole N-throw switches for wireless applications (portable units and base stations) [2].

How does RF MEMS work?

Capacitive MEMS RF Switches During operation, a force is applied to a beam suspended like a bridge across a substrate. When the beam is pulled down by a force (such as an electrostatic force), the beam contacts a dielectric on the substrate and the signal is terminated.

What industries use MEMS?

What do you need to know about RF MEMS?

An overview of RF MEMS technologies and applications. by Jacopo Iannacci, Ph.D. RF MEMS devices are microsystems manufactured in a suitable technology platform, typically characterized by having movable micro-parts capable of reconfiguring the RF characteristics of a device.

What are the applications of a microwave MEMS?

Many MEMS based microwave components are aimed atreducing insertion loss andincreasing bandwidth. This third aspect is valid for surface micromachined devices such as RF switches, tunable capacitors and micro inductors. Conventional RF switching systems such as PIN diodes tend to be inefficient at higher frequencies.
