you will need opamps with frequency response range (to the range of 100s of MHz). I dont think such opamps will be easily available, but of course it depends on what resources are available at your location.

foxclab01 said:I am trying to replace a classic LC circuit with a gyrator or any active inductor ( so that I get rid of the passive inductor ).
The problem is that I want to use the circuit for high frequences. To be more specific, I want to use it as a filter that only allows a 38.9 Mhz frequency to pass and stops all the others.
Is there a way to do it? Is the noise ratio good? Is it possible to get a schematic?

On the other hand, the passive LC circuit seems to have a better behavior as a filter ( more accurate ).
