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

I want to filter the all harmonics above 125MHz using Low pass filter (BW : 300MHz, specification) but I could not suppress them even I used a good response LPF Note that, this harmonics are from mixing an RF signal and an LO signal.
Is an idea about it ??
Thnak you in advance
