Hello everyone

I’m naserturk from Turkey Istanbul

Firs accept my apology for my bad English


I designed a universal frequency counter

I need a good and sensitive preamp circuit for low frequency input of my frequency counter

Input frequency range of this input is between 0 to 150 MHz


for now I use MC10H116 but this IC is ECL and I have to use a lot of component with this IC




I don’t like sensitivity of this circuit at all


I know that some of analog device IC’s can help me


Can you help me to find a good IC for this preamp?


Tanks a lot for you helps
