RF Input
Figure 7. Simplified schematic of production test board. Primary purpose is to show 15 Ohm series resistor placement in
gate supply. Transmission line tapers, tee intersections, bias lines and parasitic values are not shown.
Gamma Load and Source at Optimum OIP3 and P1dB Tuning Conditions
The device’s optimum OIP3 and P1dB measurements were determined using a load pull system at 4.5V,
200 mA quiesent bias:
