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.
Absolute Maximum Ratings
Parameter | Unit | Rating |
RF Input Level | dBmV | 65 |
DC Supply Over-Voltage (5 minutes) | V | 30 |
Storage Temperature | °C | - 40 to +100 |
Operating Mounting Base Temperature | °C | - 20 to +90 |
Alarm: Exceeding any one or a combination of the Absolute Maximum Rating conditions may cause permanent damage to the device. Extended application of Absolute Maximum Rating conditions to the device may reduce device reliability. Specified typical performance or functional operation of the device under Absolute Maximum Rating conditions is not implied.
