Patent ID: 8093972

Claim:
An electromechanical device comprising: a first electrode having a first part, a second part, and a third part integrated with one another; a second electrode having a first opposing part opposite the first part; and a third electrode having a second opposing part opposite the second part through an intervening gap or dielectric layer, and a third opposing part opposite the third part, wherein the third electrode includes an input node that receives a first drive voltage referenced to a DC potential of the first electrode, wherein the intervening gap is set to a first predetermined distance when the first drive voltage is a first voltage, and the intervening gap is set to a second predetermined distance when the first drive voltage is a second voltage, wherein the first part is separated from the first opposing part and electrically isolated from the first opposing part when the first drive voltage is the first voltage, wherein, when the first drive voltage is the second voltage, the first part contacts the first opposing part and is electrically conductive with the first opposing part, and an RF signal input to the first electrode is substantially output from the second electrode, wherein the third part and the third opposing part constitute a first electrical capacitance of a predetermined capacity, wherein the second part and the second opposing part constitute a second electrical capacitance of a predetermined capacity when the first drive voltage is the first voltage, wherein the first part and the first opposing part constitute a third electrical capacitance of a predetermined capacity when the first drive voltage is the first voltage, and wherein the capacity of the first electrical capacitance is greater than the second electrical capacitance and the third electrical capacitance.
