Abstract
 
RF Micro-electro-mechanical-systems (MEMS) has recently proved extremely low-loss components (switches, phase shifters, tunable filters) from 1 GHz to 100 GHz. In fact, we can now build a 3-bit phase shifter with an insertion loss of 0.6 dB/bit at 7-15 GHz and 0.9 dB/bit at 75-100 GHz.
 
Also, tunable filters with extremely good linearity have been demonstrated at 18-22 GHz and with an IIP3 of > 80 dBm. We currenly understand many aspects of MEMS switches including their fabrication, mechanical electrical modeling and their circuit design. However, can we use them now ? RF MEMS still have reliability, packaging and yield problems, and we are working
furiously trying to solve these problems. This talk will present the last happening in this very dynamic field.
