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.
†
Reference Application Note M538 for lead-free solder reflow
recommendations.
Meets JEDEC moisture sensitivity level 1 requirements.
