BCR 400R Active Bias Controller
Characteristics • Supplies stable bias current even at low battery voltage
and extreme ambient temperature variation
• Low voltage drop of 0.
7V Application notes • Stabilizing bias current of
NPN transistors and FETs from
from less than 0.
2mA up to more than 200mA
• Ideal supplement for SIEGET and other RF
transistors • also usable as current source up to 5mA
