Figure 5. Block diagram of 2 GHz production test board used for Noise Figure, Associated Gain, P1dB, and OIP3 measurements. This circuit represents a
trade-off between an optimal noise match and associated impedance matching circuit losses. Circuit losses have been de-embedded from actual measure-
ments.
