This circuit is from the Linear Applications Handbook of the National Semiconductor of 1994. Transistors are common, but the integrated circuit is not easy to obtain today.
We find this circuit measuring from 1 to 1000 mW of power from small transmitters and oscillators in...
We found this circuit in a 1967 documentation. The circuit can be designed based on current...
