    • In one implementation, a switching circuit includes a pass switch including group III-V, for example III-Nitride, transistors coupled between an input of the switching circuit and an output of the switching circuit. The switching circuit further includes a shunt switch configured to ground the input of the switching circuit while the pass switch is disabled. The switching circuit also includes a gate control transistor configured to reduce resistance between a control terminal of the pass switch and/or the shunt switch and gate of the group III-V transistor of the pass switch and/or the shunt switch so as to enable and disable the pass switch and/or shunt switch. The gate control transistor can be coupled across a gate resistor of the pass switch and/or the shunt switch. The gate control transistor can reduce the resistance in order to lower the OFF state impedance of the pass switch and/or the shunt switch.
