Title:
SWITCH MODULE AND WIRELESS COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/097768
Kind Code:
A1
Abstract:
An objective of the present invention is to provide a switch module whereby, while effecting miniaturization and component simplification, it is possible to avoid interference between bands. A switch module (1) comprises a switch IC (3), further comprising: a shared terminal (ANT); a plurality of individual terminals which are connected to signal lines (SL1-SL10) respectively corresponding thereto; and a switch part (7) which selectively connects the shared terminal (ANT) with one of the individual terminals. The switch part (7) further comprises: a plurality of first switches, one end of each first switch being connected to the shared terminal (ANT) within the switch IC (3); and at least one second switch, one end whereof is connected to the shared terminal (ANT) via a connection wiring electrode which is disposed upon a wiring substrate. One end of the second switch is thereby not directly connected to the shared terminal (ANT) within the switch IC (3), and it is thus possible to avoid interference between a communication signal which is transmitted to the first switches and a communication signal which is transmitted to the second switch.
