RX TOI degradation with IF limiter

I have an issue - my receiver TOI degrades significantly when measure after ADC limiter.... TOI for the receiver is as expected when measured after IF Amplifier; however, i notice significant degradation when TOI is measured after IF filter (the IF filter is the 2nd part after the IF amplifier, it comes after the limiter).

Is there a way to match the Limiter and the filter so that TOI is not degraded?

Any help would be deeply appreciated.

Thanks!
