Notes:
1. Fmin values at 2 GHz and higher are based on measurements while the Fmins below 2 GHz have been extrapolated. 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 a true Fmin
is calculated.
2. S and noise parameters are measured on PCB. The PCB material is 10 mils Roger RO4350. Figure 35 shows the input and output reference plane.
