end of the gate lead. The output reference plane is at the end of the drain lead. The parameters include the effect of four plated
through via holes connecting source landing pads on top of the test carrier to the microstrip ground plane on the bottom side of the
carrier. Two 0.020 inch diameter via holes are placed within 0.010 inch from each source lead contact point, one via on each side of
that point.
