Notes:
1. Measurements at 2 GHz were made on a fixed tuned production test board that was tuned for optimal OIP3 match with reasonable noise fig-
ure at 2.7 V, 10 mA bias. This circuit represents a trade-off between optimal noise match, maximum OIP3 match and a realizable match based
on production test board requirements. Measurements taken above and below 2 GHz was made using a double stub tuner at the input tuned
for low noise and a double stub tuner at the output tuned for maximum OIP3. Circuit losses have been de-embedded from actual measure-
ments.
2. 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 Fmin is calculated. Refer to the noise parameter measurement section for more information.
