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？
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.
