Abstract:
A radio-frequency circuit module includes a multilayer body and a surface-mount component mounted on a front surface of the multilayer body. The surface-mount component includes variable capacitance elements integrated therein. Inductors including conductor patterns are provided in the multilayer body. On a back surface of the multilayer body, a first external connection terminal and a second external connection terminal are sandwiched between ground connection terminals. Ground via-conductors connected to ground connection terminals extend to the front surface of the multilayer body. The ground via-conductors are connected to each other in a layer near the front surface by a ground connection conductor which extends in a direction perpendicular or substantially perpendicular to the extending direction.
