ABSTRACT:
A radio-frequency device has a distributor and a tuner. The distributor has an input terminal which is disposed on one side face of a case; an output terminal which is disposed on another side face; and an output terminal which is disposed on the upper side face. The output terminal, and an input terminal of the tuner are respectively protruded at positions which are separated from the bottom face by a substantially same distance. A metal flat plate portion is led out from the side of the distributor and coupled to a receiving portion of the tuner on the side of the input terminal. Therefore, the output terminal of the distributor is directly connected to the input terminal of the tuner, so that a radio-frequency cable for connecting the units to each other is not necessary. A space reduction and a low production cost can be realized.
