Notes:
1. P1dB and OIP3 measurements are performed with passive biasing. Idsq is set with zero RF drive applied. As P1dB is approached, the drain current may
increase or decrease depending on frequency and DC bias point. At lower values of Idsq the device is running in a Class AB mode and current tends to rise
as P1dB is approached. As an example, at a Vds = 3.0V and Idsq = 10 mA, Id increases to 30 mA as P1dB of 16.5 is approached. This rise in current is no
longer present as Idsq approaches 60 mA.
2. Measurements made on a fixed tuned test system set for optimum noise match. Circuit losses have been de-embedded for the actual measurements.
