commerical RF MEMS?

Hi, everyone.

I have a question about the reliable commercial RF MEMS that can be used in UHF and microwave spectrum. Is it the MEMs switch technique mature enough? Thanks.

I guess it depends. They have a limited number of switching cycles before they fail, unlike something like a PIN switch that can theoretically switch an infinite number of times. They also require a very large DC voltage, which makes them less useful. However, if you only have to switch a few ten thousand times and you need very low loss, I guess they are ready now.

yes it could use in mobile systems ,mems antenna,
satelite systems,.............
