<10W booster amp for RF susceptibility?

[Joerg]

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?

I made up a wideband linear amplifier a couple of decades ago that put out
about 5 watts at 30 dB gain from 20-500 MHz. flat. It was built around a
Mini-Ckts module, and if you think that may be what you are looking for,
I'll tear it apart to see what the module part number is. If you need to go
lower than 20, I'm not sure what the current options are, but a second LF
unit wouldn't be all that hard to incorporate into the same chassis.

Yes, that's feasible with Mini-Circuits modules. But it won't go below
20Mhz :-(

So what bottom end do you need? You didn't specify in the OP.

Sorry. Ideally 150kHz but up to a MHz would do.

That sounds like an HF homebrew job. Helge Granberg (Motorola) wrote some
very good articles on HF linear rigs about twenty years ago. I can research
the pertinent AN numbers if you like. As I recall, his bottom end was

Yes, I got his app notes. But I wasn't looking for yet another homebrew
job. Let's see, there is already the deck post which also the A/C is
bolted to which make this honey-do job a major pain in the neck, then
there's the chimney flashing fix that will require me to don fall gear
and teeter on some edge up there, then there is ...
