Found in a European magazine from the 1980s, this circuit can amplify signals from 10 kHz up to over 220 MHz with good gain. MOSFET supports equivalents.
We found this 4-channel mixer in the August 1999 issue of Electronics Now magazine. The circuit can...
The configuration shown makes use of a simple source and the gain is given by the relationship between R3...
This circuit was found in a 1995 documentation and is very simple to assemble, as the components are...
