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

5.

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 GHz - 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.

6.

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.

7.

If negative control is used, DC blocking capacitors are not

required on RF ports.
