BCR400R

Active Bias Controller

Siemens AG 

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
