ABSTRACT:
The high-frequency module of the present invention is formed of two sections: first high-frequency circuit5having a first filter circuit; and second high-frequency circuit6having a second filter circuit. At least any one of the two high-frequency circuits has a conductive case. The structure is highly effective in attenuating a spurious signal, thereby solving the problem that the output level of the spurious signal fed from the high-frequency module is undesirably increased.
