HIGH-FREQUENCY MODULE

Abstract: a first circuit that inputs/outputs a first frequency band and a second circuit that inputs/outputs a second frequency band are included. a first receiving unit in the first circuit is connected to a first external connection terminal or a second external connection terminal with a band pass filter and a first switch in a high-frequency switch. a first transmitting unit or a second receiving unit in the first circuit is connected with a second switch in the high-frequency switch. the second switch is connected to a diplexer connected to a third external connection terminal. a second transmitting unit in the second circuit is connected to the diplexer or a fourth external connection terminal with a third switch in the high-frequency switch. a third receiving unit or a fourth receiving unit in the second circuit is connected to the fourth external connection terminal with the third switch.
