Circulating Currents in Filters - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Good day.

I am looking for information (books, magazine articles, general guidelines, etc.) about the circulating current (this is what I call it) in a filter or matching network.

For example: the output of a power amplifier goes through the matching network and then a low-pass filter. Current will "circulate" between the capacitors and inductors, sometimes very high current.

If my memory serves me correctly, the Q of the circuit and/or the individual components has a direct effect on the this current.

Thank you
MM
