Patent ID: 7436679

Claim:
A communication radio-frequency module that has a semiconductor device to which an antenna element is connected, comprising: a supporting body; a wiring board that is fixed onto a first surface of the supporting body; the semiconductor device that is flip-chip mounted onto the wiring board; the antenna element that is disposed on a second surface that is opposite from the first surface of the supporting body; a waveguide that penetrates the supporting body, and has an opening through the first surface and the second surface; and a waveguide converter that is disposed at a location on the surface of the wiring board on the side of the supporting body, the location being set to face the opening of the waveguide, the semiconductor device being connected to the antenna element via a vertical wiring unit that is disposed on the wiring board, the waveguide converter, and the waveguide, the wiring board comprising a board core member that is made of a first resin material, the supporting body comprising: a supporting body core member that is made of a second resin material; and an inorganic film that is located on the side of the first surface and has a higher coefficient of elasticity than the second resin material.
