For my research purpose, I am planning to design one power amplifier (basically, a current amplifier) with the following specification-
- Frequency range: 0-100MHz (or at least 0-30MHz)
- Output voltage: 30Vpp
- Minimum output load: 3Amp
- The input current is expected to be very low as it will be feed from a simple function generator (max output current is not specified in the function generator manual, but I think, they should be less than 30mAmp)
Initially, I was planning to use an RF op-amp but later realized, none of the commercial op-amps can drive such high current. What would be the most optimized design for this circuit?
