gate supply. Transmission line tapers, tee intersections, bias lines and parasitic values are not shown.
Gamma Load and Source at Optimum OIP3 Tuning Conditions
The device’s optimum OIP3 measurements were determined using a Maury load pull system at 4V, 135 mA
quiesent bias. The gamma load and source over frequency are shown in the table below:
