  • Publication number: 20080129425
    Abstract: An electrical switching device, especially a high-frequency switching device, with an oblong, electrical switch element, which is arranged with one contact end between two counter-contact elements with a transverse distance from one another, and which can be moved transversely relative to its longitudinal direction optionally towards the one or the other counter-contact element by two adjustment elements disposed on both sides near to the switch element. In order to prevent or at least to minimize frictional processes during switching, the switch element consists at least partially of magnetic material, wherein the adjustment elements are formed by magnets, and wherein, the efficacy of the magnet, which is arranged on the side respectively opposite to the counter-contact element to be contacted, can be reduced or cancelled to allow a switching process.

  • Patent number: 7324350
    Abstract: An apparatus and method to provide a micro-electromechanical systems (MEMS) radio frequency (RF) switch module with a vertical via. The MEMS RF switch module includes a MEMS die coupled to a cap section. The vertical via passes through the cap section to electrically couple an RF switch array of the MEMS die to a printed circuit board (PCB). In one embodiment, the MEMS die includes a trace ring surrounding at least a portion of the RF switch array so that a signal may enter or exit the MEMS RF switch module using the vertical via without crossing the trace ring.

  • Patent number: 4891613
    Abstract: This microwave transfer device is a hollow body having an internal cavity and lateral input and output openings communicating with the cavity. A post in the cavity divides it into passages extending between input and output openings for passing microwave signals therebetween. Axially reciprocatable shorting pins are supported on the body and are selectively insertable in the passages to close off the passages, and retractable from the passages to open the same. By proper selective insertion and retraction of the pins, microwave signals applied at the input openings can be combined, divided, or switched, respectively, to the output openings.
