Recommended PCB Layout

Cross Section View

The PCB dielectric between RF traces and RF ground lay-

ers 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” (0.20 mm) yielding a 50

Ω line width of 0.015” (0.38 mm). The recommended RF

metalization is 1 ounce copper.

Handling Procedures

Please observe the following precautions to avoid

damage:

Static Sensitivity

Gallium Arsenide Integrated Circuits are sensitive

to electrostatic discharge (ESD) and can be

damaged by static electricity. Proper ESD control

techniques should be used when handling these

devices.
