This circuit doubles the frequency of signals from 10 to 50 MHz. We found it in a 1969 Electronic Design. The components are from the period.
The block shown in the figure is a basic source with a configuration widely used in technical...
The output current of this source is determined by resistor R. For 20 ohms, we have 50 mA. For 10...
This circuit, for its simplicity and the fact of using a super-regenerative detector only works...
