Radio-frequency module, transmission power amplifier, and communication apparatus

A transmission power amplifier comprising:

• an amplifier first main surface and an amplifier second main surface on opposites sides of the transmission power amplifier from one another;
• a first input-output electrode connected to the amplifier first main surface and through which a radio-frequency signal input into the transmission power amplifier or a radio-frequency signal output from the transmission power amplifier is transmitted;
• a second input-output electrode connected to the amplifier second main surface and through which a radio-frequency signal input into the transmission power amplifier or a radio-frequency signal output from the transmission power amplifier is transmitted;
• and
• a ground electrode arranged on the amplifier second main surface.

A communication apparatus comprising:

• an antenna element;
• a radio-frequency signal processing circuit that processes a radio-frequency signal transmitted and received through the antenna element;
• and
• a radio-frequency module configured to transmit the radio-frequency signal between the antenna element and the radio-frequency signal processing circuit, the radio-frequency module includes
• a mounting substrate having a first main surface and a second main surface on opposite sides of the mounting substrate,
• an external connection terminal arranged on the first main surface, and
• a first transmission power amplifier arranged on the first main surface, wherein
• the first transmission power amplifier includes
• an amplifier first main surface closest to the first main surface,
• an amplifier second main surface that faces away from the amplifier first main surface,
• a first input-output electrode arranged on the amplifier first main surface and through which a radio-frequency signal input into the first transmission power amplifier or a radio-frequency signal output from the first transmission power amplifier is transmitted, and
• a first ground electrode arranged on the amplifier second main surface.
