RF MEMS reliability

TRANSDUCERS '03. 12th International Conference on Solid-State Sensors, Actuators and Microsystems. Digest of Technical Papers (Cat. No.03TH8664), 2004
Device reliability is a key factor in the ultimate insertion of RF MEMS devices into operational systems. In particular, cycle lifetimes of contacting devices such as RF switches can be technically challenging due to the requirement of good contact electrical performance under operational stresses.
