Hello

I need to find an amplifier which has to work on both dc and ac input, between 2 MHz to 20 MHz frequency range (need to amplify about 20V) and the power supply voltage should be less than 10V. Is it possible to find such an amplifier? If u have any idea, could you share with me the data sheets/model numbers? Im only helping for a professor of mine, so this is all the information I have got. But in case an extra information will be useful, let me know.

Thank You

 

... (need to amplify about 20V) and the power supply voltage should be less than 10V.

Good luck on meeting that requirement.

 

1. DC is not in the 2MHz-20MHz range.
2. The output voltage will be less than the power supply voltage.

 

How much gain do you need?

What kind of signal will the amplifier handle (sine waves, video, pulses, encoded data, etc.)?

 

new power supplies can use both AC and DC as inputs.
90 VAC - 250 VAC and 300 - 500 VDC being An axample of name plate input ranges. operation from a 10 volt DC supply is NOT an option.

 

How much gain do you need?

What kind of signal will the amplifier handle (sine waves, video, pulses, encoded data, etc.)?

Gain should be about 20dB i guess. Im not very sure about the kind of signal sir, but the application is electrostatic actuation, if that may help.

 

What is the nature of the load? (Sounds like it might be highly capacitive)

 

Yes sir, it is capacitive
