1.6 Ghz sounds impressive but it is likely the speed of transistor (bandwidth of the signal that passes thru it) not its switching frequency which is likely much lower, any idea how low it is? It used to be that these MEMs switches are only good for configuration purposes, you can't switch anything in real time...Kris

Stats on this first device are still scant, but the team is aiming for switches based on it to eventually operate in the GHz range.

I received this comment from Sunil Bhave, principal investigator from Cornell University: "Hello, the device is not a switch, its a resonator. The center frequency of the device is 1.61GHz. and it has a Quality Factor of ~26,000. The bandwidth of the JFET that is integrated with the resonator is in the 10s of GHz range, so there is no bandwidth concerns with the pickoff mechanism"

Do they say anything about the packaging? A MEMS resonator needs a cavity under decent vacuum, nothing conventional IC packaging can provide.
