Note:
1. Gamma out is the re ection coe cient of the matching circuit presented to the output of the device.
2. 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  gure measurements made at 16 di erent 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.
