Abstract :
Summary form only given. The evolution of on-wafer packaging using Si micromachining is still in its infancy. In addition to the use of on-wafer packaging, the use of MEMS for the development of high-performance, low-cost circuit components that can be integrated in a three dimensional environment has revolutionized circuit architectures. The article presents a summary of the work at the University of Michigan in MEMS switches for microwave and mm-wave applications. An insertion loss of only 0.02 dB at 10-30 GHz is measured, while high isolation (150 dB) has been achieved by use of tuned switch packages for 20-40 GHz applications. The article concludes with the use of MEMS switches in tunable filters.
