Mechanical Design of RF MEMS Capacitive Switches

 This paper analyses the mechanical behaviour of various suspensions of electrostatically actuated RF MEMS switches. A family of capacitive switches is described, with suspensions varying step by step from cantilevers to meander shaped double clamped beams. The result is a capacitive shunt switch with a designed actuation voltage of 4.5 V, and 20dB isolation and 0.04 dB insertion loss at a fre...

ESD effects in capacitive RF MEMS switches

RF MEMS have shown very attractive characteristics in automotive, communication, aeronautic and aerospace applications, thanks to its low mass and volume, low losses, low power consumption, high isolation and a wide operative frequency range. Moreover they have demonstrated good integration with electronics which show their ability to built-in innovative RF architectures [1]. Nevertheless the a...

RF MEMS Switches and Switch Matrices

RF-MEMS technology has the potential of replacing many of the mechanical and semiconductor switches used in mobile and satellite communication systems. In many cases, such RF-MEMS switches would not only reduce substantially the size and power consumption, but also promise superior performance. The paper reviews the recent development of RF MEMS switches and switch matrices. Several configurati...

Compact Model of Dielectric Charging in RF MEMS Capacitive Switches

RF MEMS capacitive switches show great potential for use in wireless communication device. However, their widespread insertion in commercial products requires further improvements in their longterm reliability. Dielectric charging is one of the factors that impact switch reliability. Dielectric charging is understood to mean the accumulation of electric charge in the insulating dielectric layer...
