Thin film packaged redundancy RF MEMS switches for space applications

Abstract

A low cost packaging solution has been successfully implemented on RF MEMS switches. The encapsulation is made at wafer level by thin film packaging, it allows keeping very small footprint for the device and is fully compatible with wire bonding and flip chip assembly. In addition to their highly shrinked size, packaged switches excellent microwave performances and promising behaviors in terms of reliability, especially for redundancy schemes required by space applications.
