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.
Operating the AM42-0039
The AM42-0039 is static sensitive. Please handle
with care. To operate the device, follow these steps.
1.
Apply -2.0 Volts to VGG.
2.
Ramp VDD to +8V.
3.
Adjust VGG to set quiescent drain current .
4.
Apply RF.
5.
Power down in reverse sequence.
Turn gate
voltage off last.
