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.
The circuit is from the 1994 National Instruments Linear Applications Handbook. The LM194 consists of...
We found this circuit in a Gernsback documentation from 1960. The circuit is intended for...
This circuit was suggested by a 1967 Electronic Design. Modern equivalent transistors can be used....
