For example, in order to control the first shunt switching circuit SH1 to the off state, the second gate voltage Vg2 may be 0V and the bias voltage Vbias may be 1.2V, and accordingly, with respect to the signal line, there is an effect of supplying a negative voltage to the gate, and thus the first shunt switching circuit SH1 may be in the more definite off state.

The second resistance circuit 300 may be connected between the bias voltage Vbias terminal of the voltage generation circuit 100 and a ground terminal TG of the first shunt switching circuit SH1 and may provide the bias voltage Vbias output from the voltage generation circuit 100 to the ground terminal TG.

For example, the first resistance circuit 200 may include a first resistor R20 connected between the bias voltage Vbias terminal of the voltage generation circuit 100 and the signal line SL. The second resistance circuit 300 may include a second resistor R30 connected between the bias voltage Vbias terminal of the voltage generation circuit 100 and the ground terminal TG.

For example, a first resistance value of the first resistance circuit 200 may be the same as a combined resistance of a resistance value of the first shunt switching circuit SH1 in the off state and a resistance value of the second resistance circuit 300.
