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.
1. Reference Application Note M513 for reel size information.
2. All sample boards include 5 loose parts.
* Restrictions on Hazardous Substances, European Union Directive 2011/65/EU.

5. For positive voltage control, external DC blocking capacitors
are required on all RF ports (pins 1, 2 and 3)
6. Differential voltage, V(state 1) - V(state 0), must be +2.8 V
minimum and less than 8 V.
7. 0 = -8 V to 0.2 V, 1 = -0.2 V to 8 V
3. Exceeding any one or combination of these limits may cause
permanent damage to this device.
4. MACOM does not recommend sustained operation near these
survivability limits.
