Sorry for any confusion the requirement isn't flat to 10KHz, we're about 34mA at 10KHz rising to 1.7A at 500KHz, then it is constant to 400MHz.
It's based on DO-160 RFCS but to custom levels, unlike DO-160 it doesn't ramp down at 100MHz. I've used a CIP9136A, at lower test levels with the benefit of running the whole frequency range without changing probes, totally unaware that you could make 1.7A with forced air cooling. I guess the forced air helps with the heating effect where you get diminishing returns more power = more heat and a little increase in ImA Rich On Thu, May 4, 2017 at 10:35 AM, Ken Javor <[email protected]> wrote: > And the FCC injection clamp I recommended suffices for that on the low > side, which is why I made that comment.
