Zusammenfassung:	PURPOSE: A communication module with improved filter features is provided to improve the EVM(Error Vector Magnitude) features of a filter, thereby increasing transmission quality. CONSTITUTION: A filter(200) is mounted on a PCB(100). A shielding case(300) covers the filter and shields the PCB from the outside. The shielding case has a penetrated hole(350). The penetrated hole is formed by eliminating a partial area facing the side opposite to the mounting side of the filter.
