6. For positive voltage control, external DC blocking capacitors are required on all RF ports.

7. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 300 MHz - 1 GHz, 39 pF for 0.5 GHz - 4 GHz.

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.
