High Power (>1W) Application RF MEMS Lifetime Performance Evaluation
1.0 INTRODUCTION Solid-state RF devices are currently utilized in a wide array of application areas, including satellite communications systems, wireless communications systems, automotive radars, and defense applications. Currently, PIN diode or Field Effect Transistor (FET)-based switches are utilized for their high switching speeds, high power handling, low drive voltage, low cost, and techn...
متن کاملApplication of RF-MEMS-Based Split Ring Resonators (SRRs) to the Implementation of Reconfigurable Stopband Filters: A Review
In this review paper, several strategies for the implementation of reconfigurable split ring resonators (SRRs) based on RF-MEMS switches are presented. Essentially three types of RF-MEMS combined with split rings are considered: (i) bridge-type RF-MEMS on top of complementary split ring resonators CSRRs; (ii) cantilever-type RF-MEMS on top of SRRs; and (iii) cantilever-type RF-MEMS integrated w...
متن کاملDesign and simulation of a RF MEMS shunt capacitive switch with low actuation voltage, low loss and high isolation
According to contact type, RF MEMS switches are generally classified into two categories: Capacitive switches and Metal-to-Metal ones. The capacitive switches are capable to tolerate a higher frequency range and more power than M-to-M switches. This paper presents a cantilever shunt capacitive RF MEMS switch with characteristics such as low trigger voltage, high capacitive ratio, short switchin...
متن کاملA Flexible Fabrication Process for RF MEMS Devices
RF MEMS are assuming a great importance in the fast evolving telecommunication market and space applications. In the last years a flexible technology platform has been developed and continuously optimized at FBK (Italy) for the fabrication of RF MEMS basic components as well as complex RF circuits working in the frequency range from sub-GHz up to more than 100 GHz. The paper reports about the f...
