RF-MEMS switch

A switch RF-MEMS wherein a between the RF signal conductivity cell HAVING signal conduction's direction with a limiting is installed on the RF signal conducting unit of removable electrode. The switch is mobile electrode mobile device, which is made of all removable and relative to the or the RF signal conducting unit same are. A clamping electrodes removable RF signal conducting unit the electric connection with the following a lead; when removable electrode from separating RF signal terminal unit are when the RF signal conductivity cell signal thereof is clamped with, wherein a comprises an is the signal composite signal vibration amplitude of mobile electrode RF signal conducting unit of reflection is smaller than of each signal vibration amplitude of mobile electrode RF signal conducting unit of reflection.
