FREQUENCY (GHz)
Figure 42. MSG/MAG and |S₂₁|² vs.
Frequency at 4.5V, 120 mA.
Notes:
1. F_min values at 2 GHz and higher are based on measurements while the F_mins below 2 GHz have been extrapolated. The F_min 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 a true F_min 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.
