  • Contact structure for electromechanical switch
    Patent number: 9196429
    Abstract: The present disclosure discloses a contact structure for electromechanical switch. The contact structure is using the design including a PCB and a moving contact to allow the actuations and have great switch characteristics whose range is from DC to high frequency.
    Type: Grant

  • Radio frequency combiner/divider
    Patent number: 9160051
    Abstract: An RF combiner/divider includes an input switch, an output switch, an impedance-matching transmission network for connecting the input switch to the output switch, and a control circuit connected to the input switch and the impedance-matching transmission network. The RF combiner/divider is used for automatic impedance transformation for impedance-matching. The RF combiner/divider is suitable for use in an RF system with a changeable number of combiner/divider branches.

  • Contact structure for electromechanical switch
    Patent number: 8884726
    Abstract: A contact structure for electromechanical switch includes a static contact and a moving contact to allow many kinds of actuations and provide great switch characteristics, such as high isolation and low insertion loss, for using in the applicable range from DC to high frequency microwave. In the contact structure, there is a gap disposed between the static contact and the moving contact so that the static contact and the moving contact are parallel with each other.
