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.
