Patent ID: 7102896

Claim:
An electronic component module comprising: a mounting substrate including a shield layer and transmission lines and on which at least a first cavity and at least a second cavity are formed; at least a first electronic component positioned in said first cavity and configured to be used in a first frequency band; at least a second electronic component positioned in said second cavity and configured to be used in a second frequency band; lid members equipped with a shielding feature configured to seal said first cavity and said second cavity; one or more antennas formed on a surface of said mounting substrate, said one or more antennas being connected to at least one of said first and second electronic components; and a plurality of terminals formed on said mounting substrate, said plurality of terminals connected to said first electronic component and said second electronic component via said transmission lines; wherein at least one of said first and second electronic components is mounted on said mounting substrate via a substrate component having a higher heat resistance than a heat resistance of said mounting substrate and said mounting substrate is composed of a member having a lower dielectric constant than a dielectric constant of said substrate component.
