Frequency at 2V, 20 mA.
Notes:
1. The Fmin values are based on a set of 16 noise figure measurements made at 16 different impedances using an ATN NP5 test system. From
these measurements Fmin is calculated. Refer to the noise parameter measurement section for more information.
2. S and noise parameters are measured on a microstrip line made on 0.010 inch thick alumina carrier assembly. The input reference plane is at
the end of the gate pad. The output reference plane is at the end of the drain pad.
