| Zusammenfassung: | A radio frequency front end circuit includes a diplexer, two reception filters having, as pass bands, a band of a low frequency side band group and a band of a high frequency side band group, and a transmission/reception filter in which a pass band overlaps a boundary band of the low frequency side band group and the high frequency side band group, in which the diplexer includes a low frequency side filter connected to a common terminal and a first input/output terminal and a high frequency side filter connected to the common terminal and a second input/output terminal, the common terminal is connected to a common input/output terminal, the one reception filter is connected to the first input/output terminal, the other reception filter is connected to the second input/output terminal, and the transmission/reception filter is connected to the common input/output terminal without passing through the diplexer. |
