Abstract:
The present invention generally relates to RF MEMS devices that are capable of hot switching. The RF MEMS devices, by utilizing one or more spring mechanisms, are capable of hot switching. In certain embodiments, two or more sets of springs may be used that become engaged at specific points in the displacement of the cantilever of the MEMS device. The springs allow for a significant increase in the release voltage for a given pull in landing voltage.
