Note:
1.
Fmin values are based on a set of 16 noise figure measurements made at 16 different impedance using an ATN NP5
test system. From these measurements a true Fmin is calculated.. Refer to the noise parameter application section
for more information.
2.
S and noise parameters are measured on a microstrip line made on 0.025 inch thick alumina carrier. The input
reference plane is at the 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.
