A gate contact is formed between the source and drain contacts for modulating electric fields within the active layer. A spacer layer is formed above the active layer and a conductive field plate formed above the spacer layer, extending a distance Lf from the edge of the gate contact toward the drain contact. The field plate is electrically connected to the gate contact and provides a reduction in the peak operational electric field.
