1. External DC blocking capacitors are required on all RF ports.
39pF capacitors used for positive control voltage.
2. |-V_CTL|, V_CTL ≤ 8 V
3. If negative control is used, DC blocking capacitors are not required
on RF Ports.
Handling Procedures
The following precautions should be observed to avoid damage:
Static Sensitivity
Gallium arsenide Integrated Circuits are ESD sensitive and can
be damaged by static electricity. Proper ESD techniques should
be used when handling these devices.
