  • Patent number: 10321555
    Abstract: An RF circuit module having RF and DC contacts on a surface of a circuit board. An RF component having RF and DC contacts is disposed in a cavity of the circuit board. Electrical connectors bridge the cavity to connect the RF contacts on the circuit board to the RF contacts on the RE component and the DC, contacts on the circuit board to the DC contacts on the RF component. A plug member is disposed in the cavity which has a dielectric member with an outer portion disposed over the RF and DC contacts on the circuit board and an inner portion elevated above the RF and DC contacts the RF component. The plug member has one portion of electrical conductors disposed on an upper surface of the inner portion and another portion disposed under the outer portion on, and electrically connected to, the DC contacts on the circuit board.

  • Patent number: 10243246
    Abstract: A phase shifter is formed by providing a branchline coupler having a pair of phase adjusting sections. Each one of the phase adjusting sections is coupled to a corresponding one of a pair of shunt transmission line sections of the branchline coupler. Each one of the pair of phase adjusting sections includes: first and second conductive pads are disposed on the surface of a substrate having a gap between them; one of the pads being connected to a ground plane conductor on a bottom surface of the substrate. A series of conductive layer segment is sequentially written on the surface of the substrate in the gap electrically connected to sidewalls of the first and second pads. Phase shift through the phase shifter is measured after each one of the segments is written. The writing process is terminated when the measuring detects a predetermined phase shift through the phase shifter.

  • Patent number: 10218045
    Abstract: A microwave transmission line structure having a pair of ground strip conductors on a surface of a dielectric substrate structure. A signal strip conductor is disposed on the surface of the dielectric substrate structure between the pair of ground strip conductors. A solid dielectric layer is disposed over: the signal strip conductor; the upper surface of the dielectric substrate structure between sides of each one of the ground strip conductors; and the signal strip conductor. An electrically conductive shield member is disposed on the solid dielectric layer and on, and in direct contact with, upper surfaces of the pair of ground strip conductors. The structure is used on each one of a plurality of proximate microwave transmission lines formed on the substrate structure to electrically isolate the transmission line.
