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
