Abstract:
A high-frequency module (1), provided with: a multi-filter unit (20) having filters (30a, 30b, 30c) which have different signal passbands, a terminal (21a, 21b, 21d) serving as an input/output terminal being provided to each of the filters (30a, 30b, 30c); and a switch unit (10) having a terminal (11a) serving as a transmission/reception terminal and a terminal (11b) serving as a GND terminal, the switch unit (10) switching the destination of connection of the terminal (21b) of the filter (30b) to the terminal (11b) or the terminal (11a). In the filter (30b), the terminal (21b) is a common terminal connected to a terminal, of a filter (30a) different from the filter (30b), to be put in a reference potential. If the terminal (21a) of the filter (30a) is to be connected to a terminal (12a), the switch unit (10) switches the destination of connection of the terminal (21b) to the terminal (11b).
