| 摘要 |
A switch circuit includes an input section; an output section; a first series section having an output and comprising at least a first 4-terminal FET connected between the input section and the output section through the output of the first series section; a first shunt section comprising at least a second 4-terminal FET connected between an output of the first series section and a ground; a first control terminal section connected with a gate of the first 4-terminal FET; a second control terminal section connected with a gate of the second 4-terminal FET; and a back gate control terminal section connected with a back gate of each of the first and second 4-terminal FETs. A bias power supply section is configured to apply a reverse bias voltage between the back gate control terminal section and the ground.
