At clients I usually rent an ENI amplifier for that but they are really
bulky, heavy and overkill. And expensive. When testing a bus for
susceptibility one rarely needs more than 30Vpp into 100 ohms or so, up
to 500MHz. The other amps I've got are the usual wideband amps that
cannot produce more than about +20dBm.

Is there a booster amp that's smaller, like 10W or less?
Have you considered a HAM radio? Some can be modded for a wider set of
frequencies. E.g.:

I have but it'll be restricted to something like 2-50MHz or some
extended VHF/UHF ranges.


Or do you need a bare amp and full coverage?

Yes :-(

ENI has some smaller amps so we'll be stuck with those I guess. Still
huge and expensive. Similar for the other RF amp manufacturers. If the
market wasn't so small I'd design, build and sell some.

Clearly revealing the differences between building one for personal
use, commercial use, and for sale.


I have designed RF power stages for gear that is now in production. But
the clients own the rights plus they are all too big for this purpose.
Mine certainly do not cost the equivalent of a small car, like many of
the susceptibility amps do.

Cool, you have track record. Next time don't bork the IP deal.
