I need to amplify a signal which is oscillating between 3V and -3V at a frequency of +- 10MHz, into the 10-20kVolts range.
I've been looking for an opamp or a transistor but the max supply voltage I've found is 1.7kV
Anyone knows of an opamp/transistor meeting those requirements? Or any other means to increase the voltage of a signal...
Edit : Following different answers, here are some more informations. I'm trying to duplicate, with a few upgrades, a device that generate a wave at 1MHz, with an constant amplitude of 4kV. I've measured those data with my oscilloscope and a voltage divider quite easily. Example of such device : https://en.m.wikipedia.org/wiki/Electrosurgery @ "Electrosurgical waveforms"
I would like to be able to generate a carrier wave from 1MHz to 10 MHz and modulate its amplitude at will. And a bit more voltage is always nice ;-)
In order to have complete freedom on the waveform, I believe it is easier to generate the voltage digitally and use a DAC to convert it. This is the reason of the initial signal being between -3V and +3V. (Or between 0V and 5V, or 0V and 3V, ... In the micro-controller range)
I need to be able to change the signal on the fly (some software lags are acceptable but not powering down and changing a couple of inductances to adjust the resonance frequency)
Concerning the power output, less then 100 W is perfect.
Again, thanks a lot for your time and your inputs !!!
