Classification: CPC H | IPC H

Claim 13:
14. A communication device comprising:
a radio frequency module that conveys a radio frequency signal between an antenna and a signal processing circuit; and
the signal processing circuit that processes the radio frequency signal that is provided by the antenna, or provided to the antenna, wherein the radio frequency module includes a substrate,
a first transmission amplifier that is mounted on the substrate and that amplifies a first transmission signal in a first communication band,
a second transmission amplifier that is mounted on the substrate and that amplifies a second transmission signal in a second communication band,
a third transmission amplifier that is mounted on the substrate and that amplifies a third transmission signal in a third communication band, and
circuitry configured to
enable simultaneous transmission in the first communication band and in the third communication band,
prevent simultaneous transmission in the first communication band and the second communication band, and prevent simultaneous transmission in second communication band and in the third communication band, and
in plan view of the substrate, a distance between an output terminal of the first transmission amplifier and an output terminal of the third transmission amplifier is longer than a distance between the output terminal of the first transmission amplifier and an output terminal of the second transmission amplifier as well as a distance between the output terminal of the second transmission amplifier and the output terminal of the third transmission amplifier.
