Customer Defined
The PCB dielectric between RF traces and RF ground layers
should be chosen to reduce RF discontinuities between 50
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.

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:
I
dd ~10 mA, R1 = 75 ohms;
I
dd ~20 mA, R1 = 25 ohms;
I
dd ~30 mA, R1 = 9 ohms.
