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 a true Fmin is calculated. Refer to the noise parameter application section for more information.
2. Refer to the applications section for additional information on the test fixture used for the measurement of the s and noise parameters.
