Abstract:
1. A satellite broadcasting receiving converter which receives radio waves transmitted from a plurality of neighboring satellites, performs frequency conversion of two polarized signals transmitted from one satellite into different intermediate frequency bands using first and second mixers, and connects each first mixer and each second mixer to either one of two local oscillation circuits which differ in oscillation frequency from each other, wherein each local oscillation circuit and the respective mixers are connected to each other using an oscillation signal line on a first surface of a first printed circuit board, wherein a second surface of the first printed circuit board and a first surface of a second printed circuit board are bonded by way of a ground pattern, wherein an intermediate frequency signal line for an intermediate frequency signal outputted from each of the mixers is pulled out from one surface of the first printed circuit board to a second surface of the second printed circuit board at bonded portions, and wherein the intermediate frequency signal line and the oscillation signal line are made to cross each other.
