    摘要: A switch includes a conductive region, a membrane, and a dielectric region. The dielectric region is formed from a dielectric material and is disposed between the membrane and the conductive region. When a sufficient voltage is applied between the conductive region and the membrane, a capacitive coupling between the membrane and the conductive region is effected. The dielectric material has a resistivity sufficiently low to inhibit charge accumulation in the dielectric region during operation of the switch.

    摘要: RF MicroElectroMechanical Systems (MEMS) circuitry (15) on a first high resistivity substrate (17) is combined with circuitry (11) on a second low resistivity substrate (13) by overlapping the first high resistivity substrate (17) and MEMS circuitry (15) with the low resistivity substrate (13) and circuitry (11) with the MEMS circuitry (15) facing the second circuitry (11). A dielectric lid (19) is placed over the MEMS circuitry (15) and between the first substrate (17) and second substrate (13) with an inert gas in a gap (21) over the MEMS circuitry (15). Interconnecting conductors (25,31,35,37,39,41) extend perpendicular and through the high resistivity substrate (17) and through the dielectric lid (19) to make electrical connection with the low resistivity substrate (13).

    摘要: An apparatus and a method are provided for electronically tuning cavity filters. A tunable cavity comprises at least two pieces of material, such as metal plates or metal traces, and MEMS circuitry interconnecting the pieces of material. Multiple tunable cavities can be combined to create a tunable cavity filter. In one embodiment, a waveguide cavity filter comprises a metal insert attached to a substrate. At least two pieces of material and MEMS circuitry reside within the cavities produced by the metal insert. The MEMS circuitry can be controlled to connect or disconnect the pieces of material, which alters the electric and magnetic fields inside the cavities. In another embodiment, a MEMS positioner inside the cavity filter can physically deform or move a piece of material within the cavity. By altering the electric and magnetic fields within the cavities the resonant frequency of the cavity filter can be tuned.
