Abstract:
A capacitive type MEMS switch comprising:a) a substrate member; b) a conductor arrangement deposited on said substrate, said conductor arrangement including first and second RF conductors; c) first and second support members on said substrate; d) a bridge member having a central portion and first and second arms extending out from said central portion; e) said first and second arms being respectively connected to said first and second support members; f) a dielectric layer deposited on a portion of said conductor arrangement; g) said conductor arrangement defining an open area; h) a pull down electrode positioned within said open area; i) said pull down electrode being of a height less that that of said conductor arrangement, and being substantially surrounded by said conductor arrangement; j) said central portion of said bridge member being drawn toward said conductor arrangement upon application of a control voltage to said pull down electrode, to present a relatively low impedance, allowing a signal to propagate between said first and second RF conductors.
