Title:
HIGH-FREQUENCY MODULE
Document Type and Number:
WIPO Patent Application WO/2019/187744
Kind Code:
A1
Abstract:
The purpose of the present invention is to enable a frequency band of a counterpart carrier to be revealed freely in carrier aggregation of aggregating multiple carriers. In a high-frequency module (1), a variable phase shifter (4) causes a phase at the time of a first single mode, which is a mode of communicating only the signals of a first frequency band, and a phase at the time of a first carrier aggregation mode to be varied from each other, and also causes the phase at the time of the first single mode and a phase at the time of a second carrier aggregation mode to be varied from each other. In the present invention, a phase difference between the phase at the time of the first single mode and the phase at the time of the first carrier aggregation mode is made different from a phase difference between the phase at the time of the first single mode and the phase at the time of the second carrier aggregation mode.
