Abstract:
A high-frequency integrated circuit (IC) module comprising:a multilayer mounting board on which an IC with a plurality of high-frequency signal terminals on one side portion thereof is mounted; a plurality of IC connecting portions disposed on one surface of said multilayer mounting board on which said IC is mounted, said IC connecting portions being respectively connected with said plurality of high-frequency signal terminals of said IC; a plurality of external connection terminal portions disposed on a side portion of the other surface of said multilayer mounting board which portion corresponds to said one side portion of said IC, at wider intervals than those between the high-frequency signal terminals of said IC; a plurality of high-frequency signal lines provided within said multilayer mounting board to transmit high-frequency signals; a plurality of first through holes for respectively connecting the inner ends of said high-frequency signal lines with said IC connecting portions; a plurality of second through holes for respectively connecting the outer ends of said high-frequency signal lines with said external connection terminal portions; and a high-frequency restricting member for respectively ground-connecting the both surfaces of said multilayer mounting board and restricting propagation of high-frequency signals, provided at least between said high-frequency signal lines and along said high-frequency signal lines.
