Packaging of RF Mems Switching Functions on Alumina Substrate

Recently the strong demands in wireless communication requires expanding development for the application of RF MEMS (Radio Frequency micro electro mechanical systems) sensing devices such as micro-switches, tunable capacitors because it offers lower power consumption, lower losses, higher linearity and higher Q factors compared with conventional communications components. To accelerate commercialisation of RF MEMS products, development for packaging technologies is one of the most critical issues should be solved beforehand.
