Classification: CPC H | IPC H

Claim 6:
7. A method of operating a switch circuit for ultra-high frequency band, the method comprising:
applying an RF signal to an input stage of the switch circuit;
wherein the RF signal may be transmitted through a first terminal connected to the input stage and a second terminal connected to an output stage,
applying, by a variable gate driver, a gate input voltage to a gate terminal;
wherein the gate input voltage is adjusted to be in a second voltage level for turning off at least one transistor,
extracting, by a coupler, a portion of a leakage current of the RF signal flowing from the first terminal to the second terminal;
converting, by a diode, the portion of the leakage current extracted by the coupler into a signal in a DC level; and
adjusting, by the variable gate driver, the second voltage level of the gate input voltage based on the DC level output from the diode.
