Radio-frequency module and communication device

A communication device comprising:

• an antenna;
• a radio-frequency (RF) signal processing circuit configured to process RF signals transmitted and received by the antenna;
• and
• a RF module configured to transmit the RF signals between the antenna and the RF signal processing circuit, wherein
• the RF module includes
• a module substrate;
• a power amplifier;
• a first switch connected to an input terminal of the power amplifier;
• a second switch connected to an output terminal of the power amplifier;
• and
• a switch control circuit configured to control the first switch and the second switch,
• the first switch, the second switch, and the switch control circuit are included in a semiconductor integrated circuit (IC) being integrated into a single chip,
• the power amplifier and the semiconductor IC are mounted on or above the module substrate, and
• when the module substrate is viewed in a plan view, in the semiconductor IC, the switch control circuit is physically positioned between the first switch and the second switch in a manner that a virtual line extending from one side of the module substrate to another side of the module substrate, as viewed in the plan view, passes through the control circuit, the first switch and the second switch.

A radio-frequency module comprising:

• a module substrate having a first main surface and a second main surface on opposite sides of the module substrate;
• a power amplifier disposed on the first main surface;
• a first switch connected to an input terminal of the power amplifier;
• a second switch connected to an output terminal of the power amplifier;
• and
• a switch control circuit configured to control the first switch and the second switch, wherein
• the first switch, the second switch, and the switch control circuit are included in a semiconductor integrated circuit (IC) disposed on the second main surface.
