Figure 4. Block diagram of GHz production test board used for Noise Figure, Gain, P1dB, OIP, and OIP measurements. This circuit represents a trade-off
between an optimal noise match, maximum OIP match and associated impedance matching circuit losses. Circuit losses have been de-embedded from
actual measurements.

Notes:
2. Fmin and associated gain at minimum noise figure (Ga) 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 and Ga is calculated. Refer to the noise parameter application
section for more information.
3. P1dB and OIP3 measurements made in an InterContinental Microwave (ICM) test fixture with double stub tuners and bias tees. The input was
tuned for minimum noise figure and the output was tuned for maximum OIP3.
