Radio frequency module

A radio frequency module comprising:

• a substrate;
• a matching circuit unit mounted on one main surface of the substrate;
• and
• a switch circuit unit and an amplifier circuit unit mounted on another main surface or in an inside of the substrate,
• wherein
• the amplifier circuit unit has a first external terminal and is mounted on the substrate with the first external terminal interposed therebetween,
• the switch circuit unit has a second external terminal and is mounted on the substrate with the second external terminal interposed therebetween,
• the matching circuit unit has a first terminal and a second terminal, which are different from each other, and is mounted on the substrate with the first and second terminals interposed therebetween,
• the first terminal is electrically connected to the second external terminal of the switch circuit unit,
• the second terminal is electrically connected to the first external terminal of the amplifier circuit unit, and
• when viewed from a direction perpendicular to the one main surface of the substrate,
• the radio frequency module has at least one of a state in which the first terminal is superposed with the second external terminal of the switch circuit unit and a state in which the second terminal is superposed with the first external terminal of the amplifier circuit unit.
