Patent attributes
A communication module includes a first switch circuit that receives a first or second received signal and that outputs the first received signal from a first terminal thereof or the second received signal from a second terminal thereof, a first low-noise amplifier that amplifies the first received signal, a second low-noise amplifier that amplifies the second received signal, a first filter circuit disposed between the first switch circuit and the first low-noise amplifier, and a second filter circuit disposed between the first switch circuit and the second low-noise amplifier. The first filter circuit has greater signal loss than the second filter circuit. A signal path from the first terminal of the first switch circuit to the first low-noise amplifier via the first filter circuit has a shorter length than that from the second terminal of the first switch circuit to the second low-noise amplifier via the second filter circuit.
