Abstract:
A radio frequency module includes: a first low-noise amplifier including a first amplification element as an input stage and a second amplification element as an output stage; a second low-noise amplifier including a third amplification element as an input stage and the second amplification element as an output stage, the third amplification element being different from the first amplification element; a first matching circuit connected to an input terminal of the first low-noise amplifier; and a module substrate including a first principal surface and a second principal surface opposite to each other, wherein the first amplification element is disposed on one of the first principal surface and the second principal surface, and the first matching circuit is disposed on the other of the first principal surface and the second principal surface.
