Abstract:
Provided are a high-frequency module and a communication device with which it is possible to suppress reduction of reception sensitivity. The high-frequency module (1) comprises a switch (second switch 5b), a reception filter (second reception filter 4), a low-noise amplifier (second low-noise amplifier 8b), and a filter (second filter 7). The switch switches between a transmission path for a transmission signal and a reception path for a reception signal in communication using a time-division duplex method. The reception filter is provided at the stage after the switch, and passes a reception signal in a prescribed frequency band. The low-noise amplifier amplifies the reception signal passed through the reception filter. The filter is provided in the stage before the switch in the reception path (second reception path R2).
