which is around 6GHz. At that frequency (and
increasingly as we approach that frequency) the insertion loss,
reflection and crosstalk will be higher. Whether this creates a problem,
depends on the signaling speed and signaling budget.

Hi Ken
No, I have not considered edge-plating. I’ll look into this now.
We have some high frequency noise (400-500MHz) from differential lines
leaking out from an inner layer of a multilayer pcb. Edge

Morning all,
I?m designing an EMI filter for a DC input power line that has four

Thanks again Doug for sharing your interesting experiments!

I agree. One particular point
at the pin and from a
package model, we almost never have a model for the power path of the

Hi list members,
Could someone suggest or refer me to pointers/manufacturers of probes and
instruments to measure magnetic close field in the 10kHz to 10MHz frequency
range? High accuracy is not important, values to be measured would be around
0.5mT and up.
Thanks
