Abstract: A radio frequency module includes: a radio frequency input terminal for receiving an amplified transmission signal from the outside; radio frequency output terminals for supplying a reception signal to the outside; a filter connected between the radio frequency input terminal/the radio frequency output terminal and an antenna connection terminal, and having a passband including communication band D for TDD; and a filter connected between the radio frequency output terminal and the antenna connection terminal and having a passband including at least part of communication band A allowed for simultaneous communication with communication band D. The radio frequency input terminal is arranged in a region extending along a side of the module substrate, and the radio frequency output terminal is arranged in a region extending along a side facing the side of the module substrate.
