<P>PROBLEM TO BE SOLVED: To provide a tuner module capable of downsizing a device, and saving a cost. <P>SOLUTION: A surface pattern for mounting a first high frequency circuit and a first demodulator circuit which configure a first receiving system is formed on a surface of a substrate. A back surface pattern for mounting a second high frequency circuit and a second demodulator circuit which configure a second receiving system is formed on a back surface of the substrate. The surface pattern and the back surface pattern are formed so as to make positions of the first high frequency circuit and the first demodulator circuit on the surface the same as positions of the second high frequency circuit and the second demodulator circuit on the back surface. <P>COPYRIGHT: (C)2012,JPO&INPIT |
