Abstract:
A reception device including a plurality of tuners for receiving broadcast such as a satellite broadcast. A tuner circuit (1) includes an input terminal (11) into which a broadcast wave of a video signal and/or audio signal modulated into predetermined format is input and a mount layer (13) having a main circuit for selecting a video signal and/or audio signal contained in a predetermined frequency band from the broadcast wave. A first ground layer (15) is provided via a first dielectric layer (14) on the surface of the mount layer (13) not having the main circuit (12) and a second ground layer (17) is provided via a second dielectric layer, thereby suppressing interference between the plurality of tuners.
