  • Publication number: 20060202312
    Abstract: A communication radio-frequency module is provided that has a semiconductor device to which an antenna element is connected. This communication radio-frequency module includes: a supporting body that has a waveguide formed therein; a wiring board that is fixed onto a surface of the supporting body; the semiconductor device that is flip-chip mounted onto the wiring board by ultrasonic bonding; and the antenna element that is disposed on the other surface of the supporting body. In this module, the wiring board includes a board core member that is made of a resin material, and the supporting body includes a supporting body core member that is also made of a resin material.

  • Patent number: 6867661
    Abstract: A millimeter wave system includes a plurality of millimeter wave modules, each of which comprises a substrate; a microstrip conductor formed on one surface side of the substrate; a ground plate formed on the other surface side of the substrate; and conductive pads which are disposed on both sides of a strip conductor portion which extends from said microstrip conductor via a tapered portion, and which are connected to the ground potential of said ground plate through a via hole, wherein the strip conductors of this plurality of millimeter wave modules are connected to each other using conductive ribbon. Moreover, when a plurality of millimeter wave modules is connected to form a millimeter wave system, the effect produced by the interaction between the unnecessary conductive pads connected to the ground potential and the strip conductor can be reduced.

  • Patent number: 6807063
    Abstract: A high-frequency integrated circuit (IC) module comprising a multilayer mounting board on which an integrated circuit with a plurality of high-frequency signal terminals is mounted, and IC connecting portions disposed on one surface of the multilayer mounting board and respectively connected with the high-frequency signal terminals. The high-frequency IC module further comprises external connection terminal portions disposed at wider intervals than those between the high-frequency signal terminals, high-frequency signal lines provided within the multilayer mounting board, first through holes for connecting the inner ends of the high-frequency signal lines with the IC connecting portions, and second through holes for connecting the outer ends of the high-frequency signal lines with the external connection terminal portions.
