CPC classification number: H04B1/48 , H04B1/0057
Abstract: A high-frequency module includes a transmission signal amplifier that outputs a transmission signal to an antenna terminal side; a reception signal amplifier that amplifies a reception signal supplied from an antenna terminal; a switch that selectively connects the antenna terminal to either an output of the transmission signal amplifier or an input of the reception signal amplifier; and a directional coupler that is provided on a transmission signal path and detects a signal level of the transmission signal. The transmission signal amplifier is controlled by a first control signal supplied from a first control circuit. The reception signal amplifier is controlled by a second control signal supplied from a second control circuit. The switch is controlled by a switch control signal supplied from the first control circuit. The directional coupler is controlled by a coupler control signal supplied from the first control circuit.
