Op amp selection: Could you please recommend an op amp chip model that can amplify 10MHz, 50uV sine wave signals? [Copy link]

I want to build a high-frequency microvolt signal amplifier circuit that amplifies 50UV sinusoidal signals within 10MHz. I hope to amplify the 50uV signal to about 10mV. I can consider the solution of cascading multiple op amps. Does anyone have any suitable op amp chip model to recommend?

Such op amps are very expensive, so you might consider using an LNA chip. Pay attention to the device manual, and the lower limit of the operating frequency should cover your input signal. You can also consider using a transistor, and you can refer to the high-amplification circuit of a shortwave radio.

AD8129 with two-stage amplification is something you can consider.

You can search for operational amplifier noise measurement circuits on the Internet.

If you want to be fast and amplify small signals, you must cascade them.
