Figure 7. Simplified schematic of production test board. Primary purpose is to show 15 Ohm series resistor placement in gate supply. Transmis-
sion 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:
