| Summary: | Consequently, the size of the circuit is reduced, and the characteristics of the full band are good. The high-frequency module transmits and receives a transmission/reception signal of a first frequency band and a transmission/reception signal of a second frequency band lower than the first frequency band by time division multiplexing communication. The switch causes the output of the filter to be input to the low noise amplifier when the signal of the second frequency band is received, and causes the output of the power amplifier to be input to the filter of the region when the signal of the second frequency band is transmitted, thereby sharing the filter for the transmission and reception signals of the second frequency band. A filter is not shared for the transmission and reception signals of the first frequency band. As a result, the loss due to the switching is small for the transmission/reception signal of the second frequency band having a low frequency, and the circuit scale can be suppressed by shari |
