Patent ID: 7965989

Claim:
A high frequency module comprising: an antenna terminal connected to an antenna; a first reception signal terminal and a second reception signal terminal for outputting a reception signal in a balanced state; a transmission signal terminal for receiving a transmission signal; a separation circuit disposed between the antenna terminal and the first and second reception and transmission signal terminals, and separating the transmission signal and the reception signal from each other; a balanced signal output element provided between the separation circuit and the first and second reception signal terminals and outputting the reception signal in a balanced state; and a layered substrate for integrating the foregoing components, wherein: the layered substrate includes a plurality of dielectric layers stacked, and has a bottom surface and a top surface located on opposite sides in a direction in which the dielectric layers are stacked, and a plurality of side surfaces coupling the bottom surface and the top surface to each other; the balanced signal output element has a first output terminal and a second output terminal for outputting the reception signal in a balanced state, and is mounted on the top surface of the layered substrate; the bottom surface of the layered substrate has a plurality of sides including one closest to the first and second reception signal terminals; and as seen from above the layered substrate, the first and second output terminals of the balanced signal output element are located closest to the one of the plurality of sides of the bottom surface of the layered substrate that is closest to the first and second reception signal terminals, the high frequency module further comprising a first signal path connecting the first output terminal and the first reception signal terminal to each other, and a second signal path connecting the second output terminal and the second reception signal terminal to each other, wherein each of the first and second signal paths is formed using one or more through holes provided inside the layered substrate, and is not exposed at any side surface of the layered substrate.
