  • Patent number: 10321564
    Abstract: A printed circuit board (PCB) and PCB assembly. The PCB is formed of a laminate substrate of at least two layers of a non-conductive material forming at least one peripheral end face (PEF) surface separating top and bottom PCB surfaces. Embedded conductive wiring at one or more multiple layers carry energy to or from PCB surface mounted devices. The conductive wiring provides multiple conductive wire ends exposed at multiple locations along the PEF. A conductive contact structure is formed at the PEF surface to connect with one or more of the exposed conductive wire ends. One or more conductive pins are attached to the conductive contact at the PEF and are configured to mount the PCB on, and in a vertical and perpendicular orientation or a coplanar orientation relative to, a surface of a second PCB surface. The conductive pins provide one or more of: an electrical, thermal and/or mechanical contact.

  • Patent number: 10116031
    Abstract: A vertical-transition structure comprises a microstrip line and a combination of a coaxial connector and a metallic ring underneath the microstrip line. A first through hole is created next to the microstrip line and near one end of its signal line. The metallic ring has a second through hole. The coaxial connector has a center conductor including an extended portion to be inserted into the second through hole via its center, and subsequently through the first through hole to connect to the signal line vertically. Specially, the extended portion is not inserted through the center of the first through hole. The present structure can improve the high-frequency insertion loss of the vertical transition caused by the sudden change of electromagnetic field distributions from a coaxial line to a microstrip line and the resonant response of the coaxial connector, and therefore, increase the 1-dB transmission passband of the vertical transition substantially.

  • Patent number: 9041482
    Abstract: An attenuation reduction control structure for high-frequency signal transmission lines of a flexible circuit board includes an impedance control layer formed on a surface of a substrate. The impedance control layer includes an attenuation reduction pattern that is arranged in an extension direction of the high-frequency signal transmission lines of the substrate and corresponds to bottom angle structures of the high-frequency signal transmission lines in order to improve attenuation of a high-frequency signal transmitted through the high-frequency signal transmission lines. An opposite surface of the substrate includes a conductive shielding layer formed thereon. The conductive shielding layer is formed with an attenuation reduction pattern corresponding to top angle structures of the high-frequency signal transmission lines.

  • Patent number: 9035715
    Abstract: The present invention is directed to an impedance transformation device for use in a system having a characteristic system impedance, the device being characterized by a predetermined bandwidth having a center frequency. The device housing size is one-eighth wavelength of the center frequency. A first coupler is characterized by an even mode impedance and an odd mode impedance. The bandwidth is a function of the even mode impedance and the odd mode impedance substantially corresponds to the component port impedance. At least one second coupler is disposed in parallel with the first coupler and is characterized by the even mode impedance and the odd mode impedance.
