Notes:
1. Fmin and associated gain at minimum noise figure (Ga) values are based on a set of 16 noise figure measurements made at 16 different im‑
pedances using an ATN NP5 test system. From these measurements a true Fmin and Ga is calculated. Refer to the noise parameter application
section for more information.
2. Measurements obtained using production test board described in Figure 5.
3. Input tuned for minimum NF and the output tuned for maximum OIP3 using an InterContinental Microwave (ICM) test fixture, double stub
tuners and bias tees.
