Abstract
Disclosed is a switch circuit for an ultra-high frequency band, which includes a transistor including a first terminal connected to an input stage, a second terminal connected to an output stage, and a gate terminal, an inductor connected to the transistor in parallel, between the input stage and the output stage, a variable gate driver to apply a gate input voltage to the gate terminal and, an input resistor connected between the variable gate driver and the gate terminal. The variable gate driver adjusts the gate input voltage to be in one of a first voltage level for turning on the transistor and a second voltage level for turning off the transistor. The second voltage level varies depending on a capacitance between the first terminal and the second terminal, when the transistor is in a turn-off state.
