1. A radio frequency module comprising:
a module substrate comprising a first main surface and a second main surface facing each other and comprising a first outline that is rectangular in plan view;
a plurality of external connection terminals arranged on the second main surface and including a radio frequency input terminal configured to receive an amplified transmission signal, a first radio frequency output terminal and a second radio frequency output terminal configured to supply a first reception signal, and an antenna connection terminal;
a first filter arranged on the first main surface, the first filter connected between the radio frequency input terminal/the first radio frequency output terminal and the antenna connection terminal, and the first filter comprising a passband including a first communication band for time division duplex (TDD); and
a second filter arranged on the first main surface, the second filter connected between the second radio frequency output terminal and the antenna connection terminal, and the second filter comprising a passband including at least part of a second communication band allowed for simultaneous communication with the first communication band, wherein:
the radio frequency input terminal is arranged in a first region on the second main surface, the radio frequency input terminal extending along a first side, the first side being among four sides that form the first outline of the module substrate, and
the second radio frequency output terminal is arranged in a second region on the second main surface, the second radio frequency output terminal extending along a second side facing the first side, the second side being among the four sides that form the first outline of the module substrate.
