ABSTRACT:
A first printed circuit board is attached to an upper surface of a chassis, and a second printed circuit board is attached to a lower surface of the chassis. The chassis has a thickness of a certain degree, which can reduce a mutual effect of first and second local oscillators, and can suppress occurrence of a spurious signal. Thus, a satellite broadcast receiving device can be provided in which the mutual effect of two local oscillating circuits can be reduced and thus occurrence of a spurious signal is suppressed.
