Patent ID: 8804362

Claim:
A high-frequency module comprising: a laminate including a plurality of dielectric layers each including an electrode pattern located thereon; a power supply circuit section arranged to output a voltage to operate the high-frequency module; and a high-frequency integrated circuit mounted on a front surface of the laminate; wherein the high-frequency integrated circuit includes a test terminal connected to the power supply circuit section to check a voltage of the power supply circuit section; the laminate includes an external terminal provided on a back surface thereof to output a signal to an outside; and the test terminal and the external terminal are connected to each other through a voltage transmission path defined by the electrode pattern; wherein the high-frequency integrated circuit includes at least one common terminal and a plurality of individual terminals; the high-frequency integrated circuit is a switching element arranged to switch a path that connects the common terminal to the plurality of individual terminals; the laminate includes a plurality of communication signal paths electrically connecting the external terminal through an electrode located on an uppermost layer defining the front surface of the laminate to an electrode located on a lowermost layer defining the back surface of the laminate; and the communication signal paths are arranged so as not to overlap the voltage transmission path in a lamination direction.
