High-frequency circuit and communication device

A high-frequency circuit, comprising:

• a first switch circuit having a first terminal and a second terminal, and configured to selectively connect the first terminal and the second terminal to each other;
• and
• a voltage supply circuit configured to supply a switch control voltage to the first switch circuit,
• wherein the first switch circuit comprises:
• a first field-effect transistor (FET) having a first gate, a first drain, and a first source, the first gate being supplied with a first control voltage from the voltage supply circuit, one of the first drain and or the first source being connected to the first terminal, and the other of the first drain and the first source being connected to the second terminal,
• a second FET having a second gate, a second drain, and a second source, the second gate being supplied with a second control voltage from the voltage supply circuit, and the second drain and the second source being connected to a path connecting the first terminal, the first FET, and the second terminal, and the second drain and the second source being short-circuited.
