I have an application which requires a 20MHz high voltage (up to 500V amplitude). I already have a 20MHz signal source I just need to amplify the voltage to reach the desired value. Operational amplifiers seem easy to analyze and design with compared to transistors however I haven't seen any op amp that can work with voltages as high as 500V. I only came across some few transistors so far which can work in high voltage regimes (IGBTs & MOSFETs in sepcific).
I find myself wondering if building a 20MHz (resonant) amplifier is easier than building a 20MHz RF transformer.
I also wonder if building a high voltage 20MHz oscillator from scratch is more easier & cheaper.
I would appreciate some advices on some 'known' components which could be useful for building such an amplifier taking into account the high voltage tolerance and sufficient gain-bandwidth to accomodate 20MHz while still offering sufficient step up from about 10V to 500V.
Thanks
