Abstract
Opposite-side frequency bands are opened in a plurality of carrier aggregations. In a radio frequency module, a variable phase shifter differentiates a phase in a first single mode in which signals of a first frequency band are communicated and a phase in a first carrier aggregation mode and differentiates the phase in the first single mode and a phase in a second carrier aggregation mode. The variable phase shifter makes a phase difference between the phase in the first single mode and the phase in the first carrier aggregation mode different from a phase difference between the phase in the first single mode and the phase in the second carrier aggregation mode.
