It is an object of the present invention to provide a radio frequency module incorporating an MMIC that has a high S/N ratio while ensuring a high output. A radio frequency module according to the present invention incorporates an MMIC having a field effect transistor in which channel layers for traveling of carriers are formed by a heterostructure of two or more different kinds of materials, and height of a potential barrier of an interface between the different kinds of materials is less than 0.22 eV.
