10 MHz low frequency amplifier

[princepatel18]

Hi, i am working on a project and i want a ready made amplifier with a frequency range of 1 Hz - 10 MHz and output power of 1W. And if no one is selling than evaluation kit is also okay.

Into what load? 8 ohm? 50 ohm? 600 ohm?

Some years ago there was a company who sold wideband power opamps. They were geared towards the aerospace and military markets, and were expensive. Cn't recall their name right now.

600 ohms and what about 50 ohms i would like to know about that also...

I would be tempted to use a standard say 100MHz BW op amp followed by a couple of suitably biased transistors (npn, pnp) to provide current buffering.
