I noticed something interesting when checking two LPFs, a Bencher YA-1 and an ICE 421. I connected them both directly to the load side of my LP-100a into a dummy load and noted the ohmic, reactance and SWR readings. I tweaked them both to the same reading.
They both measured identically the same: 50 ohms, .04 reactance and 1.03 SWR into the load at the same frequency with the same signal source. When put in production; i.e., the LPF behind the LP-100a, they both registered the same constant carrier wattage, but the YA-1 passed more PEP with the same signal source. The PEP difference averaged a bit over 25% through the YA-1 over the ICE. Perhaps negligible on the receiving end but I found it interesting nonetheless. It appeared the average modulated power was pretty close which may be a more meaningful comparison.
My assumption is that the bigger coils in the ICE absorb more of the peak power than the YA-1. The power handling of the ICE is much greater and if this assumption is true, would work better with a much larger output.
Not sure if my assumption is correct so I thought I'd ask.
