Requirements: Input ± 5V 20MHz ~ 30MHz, amplified by the conditioning circuit and output ± 36V ~ ± 50V 20MHz ~ 30MHz AC signal, the current is relatively small.
Is there a suitable op amp circuit recommendation？
Calculate the required slew rate and apply filters in the product selection table. But I'm sure you won't find anything there. Your requirements are too serious to be met by a conventional operational amplifier.
I know I can't find a single op amp solution.Is there a circuit solution for a separate op amp?
I do agree with KirV that your requirements are too serious to be met by conventional op-amp.
May I know what your application is? And to check how did you come up with those requirements.
Thanks and regards.
