1. All external circuitry parts are readily available, low cost surface
mount components (0.040 inches x 0.020 inches or 0.060 inches x
0.030 inches).
2. RBIAS is chosen to set the desired current,
For:
Idd ~10 mA, R1 = 75 ohms;
Idd ~20 mA, R1 = 25 ohms;
Idd ~30 mA, R1 = 9 ohms.

Customer Defined
The PCB dielectric between RF traces and RF ground layers
should be chosen to reduce RF discontinuities between 50 Ω
lines and package pins. M/A-COM recommends an FR-4
dielectric thickness of 0.008” (0.2 mm) yielding a 50 Ω line
width of 0.015” (0.38 mm). The recommended metalization
thickness is 1 ounce copper.
