Description
The BGC405 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.

Remarks:
1)
2)
3)
4)
To provide low frequency stability C2 should be 10 times C3.
Be aware that also coupling capacitors determine the switching times.
The collector current at Q1 can be estimated by Ic=0.6V / Rx[Ω].
Place C2 as close to the device as possible.
