Power amplifier module

A power amplifier module comprising:

• a substrate;
• an amplifier circuit comprising a plurality of transistors mounted on the substrate, and a bump connected to the plurality of transistors;
• a harmonic termination circuit;
• an output matching circuit, the harmonic termination circuit and the output matching circuit being in or on the substrate and electrically connected to the amplifier circuit;
• a connection pad on the substrate and connected to the bump;
• and
• a plurality of connection wiring lines branching from the connection pad, the plurality of connection wiring lines comprising a first connection wiring line that connects the connection pad to the harmonic termination circuit, a second connection wiring line that connects the connection pad to the output matching circuit, and a third connection wiring line that connects the connection pad to an external power supply,
• wherein the first connecting wiring line, the second connecting wiring line, and the third connecting wiring line are respectively branched from the connection pad, and are electrically connected to the bump.
