This circuit that can amplify signals from 0 to 30 MHz was found in a 90s Popular Electronics. Transistors admit current equivalents. The input impedance is high.
We found this circuit in an old documentation from the 70s. The text is the original one of the...
The circuit shown in figure is suggested by Maxim in an application note. The operational...
