Description
The BGC420 is a silicon self biased RF Transistor (Q1). It offers an adjustable collector current
nearly independent from device voltage in the range from 2.0V to 4.5V. Additionally a control pin
(Vc) for switching the device off is provided. The collector current can be adjusted by connecting a
resistor (Rx) between Vcc and Vr.
