This RF amplifier step has a dynamic range of 140 dB and can amplify signals from 0.5 to 40 MHz. FET is old, but modern equivalents can be used.
This circuit was obtained from a 2005 Linear Technology application manual. The circuit is...
The tone produced by this circuit depends on the capacitor and the adjustment of the...
We found this circuit in 1969 American documentation. FETs admit equivalents, as do transistors. The...
