We found this circuit in a 90's EDN. The circuit is based on a control integrated that is still common in these types of applications. The circuit uses a PROM.
We got this circuit in a publication of 1987. This is an audio limiter, a circuit that cuts peaks...
The circuit in the figure operates at frequencies from 4 to 20 MHz and also uses a common junction FET...
Depending on the output transistor used, this transmitter can provide power from 1 to 3 W. The...
