  • Patent number: 9097757
    Abstract: A 2×2 switching element that includes first and second relays each having a first terminal, a second terminal and a third terminal, wherein the first and second relays each operate between a first state to connect the first terminal to the second terminal and a second state to connect the first terminal to the third terminal. The second terminals and third terminals, respectively, of the first and second relays are coupled to one another. The 2×2 switching element is selectively operable between: a first switching state where the first relay is operated in the first state and the second relay is operated in the second state, and a second switching state where the first relay is operated in the second state and the second relay is operated in the second state.

  • Patent number: 7535315
    Abstract: A dimensionally flexible sparse matrix comprising multiple ports connected to a plurality of interconnected universal switches is disclosed. Each universal switch has at least three terminals and is switchable to connect any pair or all three terminals together. The plurality of interconnected universal switches are independently switchable to connect any one or more ports of the sparse matrix to any subset of the other ports. The sparse matrix may also be configurable to duplicate the connectivity of a variety of dimensionally different switch matrices by designating a first subset of the multiple ports as row ports and a second subset of the remaining ports as column ports with the added flexibility of connecting row-to-row and/or column-to column. The small physical size of signal stubs in the universal switches results in a signal path between any pair of terminals that may be suitable for the transmission of signal frequencies greater than approximately 500 mega-hertz.

  • Patent number: 7378835
    Abstract: An N-wire interleaved differential multiplexer. The N-wire interleaved differential multiplexer may be formed by interleaving the channels and corresponding switches of N one-wire multiplexers. Each of the switches of the interleaved differential multiplexer may be controlled independent from the other switches to provide a signal path between a DUT stack and a measurement device. To test a first DUT, two switches of the interleaved multiplexer are closed to connect the terminals of the first DUT to the measurement device. To switch from testing the first DUT to testing a subsequent DUT, one of the previously activated switches is opened, one is kept closed, and a different switch is closed. The testing process may “walk” up or down the switch channels of the interleaved multiplexer one switch at a time to test each of the DUTs of the DUT stack.
