3. External DC blocking capacitors are required on all RF ports when using positive voltage control.

4. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz - 1 GHz, 39 pF for 0.5 - 3 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.

5. External DC blocking capacitors are required on all RF ports.

1000 pF capacitors used for positive control voltage. For

higher frequency operation, smaller value DC blocking

capacitors can be substituted.

6. If negative control is used, DC blocking capacitors are not

required on RF ports.
