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.

can you help me???
I find some information and/or reference about the relation SNR vs SWR in TX system.
tanks for the help!!

Actually there is no real connection betweem SNR and SWR in Tx systems. Of course that the SWR should be good in order to avoid mismatches and power losses which can cost you in power consumption and siye. But there is a strong relation between these parameters in Rx systems. The best example is by doing the matching of an LNA to Gopt (Input matching) in order acheive the minimal NF. Also when matching is done between each stage to decrease the return loss to the minimum so that you will achieve a lower insertion loss and a better SNR.
Hope this helps!
