  • RF filtered DC interconnect
    Patent number: 6882247
    Abstract: A filtered button DC interconnect employing a compressible conductor such as a finely wound wire mesh imbedded within a series of dielectric and ferrite cylinders. The compressible conductor is captivated within the series of dielectric and ferrite cylinders to ensure proper contact with mating surfaces of interconnected circuits. The interconnect serves as an RF filter by providing rejection of RF and microwave frequencies between the interconnected circuits.
    Type: Grant

  • MEMS tunable filters
    Patent number: 6784766
    Abstract: A method for the design of tunable filters is disclosed. MEMS switches are used to alter the resonant frequency of one or more resonators. By tuning the resonant frequency of the resonators, the filter's characteristics also are tuned. Furthermore, MEMS switches are used to alter the input coupling, including direct input coupling and capacitive input coupling. Direct input coupling is altered by using the MEMS switches to select different input connection points. Capacitive input coupling is altered by using MEMS switches to add additional input capacitance to an input coupling capacitor.
