1. An RF device, comprising:
- a first conductor for carrying an RF signal; and
a deformable membrane spaced apart from the first conductor, the deformable membrane configured to selectively filter the RF signal, the deformable membrane having at least three discrete actuatable positions for selectively filtering the RF signal.

Abstract
A voltage-controlled capacitor and methods for forming the same are described. A mechanical conductor membrane of the voltage-controlled capacitor is movable to and from a first position and a second position. An amount of capacitance can vary with the movement of the mechanical conductor membrane. A microelectromechanical systems (MEMS) voltage-controlled capacitor can be used in a variety of applications, such as, but not limited to, RF switches and RF attenuators.
