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.
Post subject: Smith Chart
Posted: Fri Jan 06, 2006 5:58
I am self studying
transmission lines and I have a
question on smith chart. Consider
the case when you're given
reflection coefficient (tau_r),
Z_not, and impedence (Z_r). You want
to find reflection coefficient at
any distance on transmission line,
i.e., tau_d, and Z_d. I'm using
Tau(d) = (1 + Z_d)/(1 - Z_d) to find
Z(d) but I don't get angle/phase
correct this way. I don't understand
where I am making a mistake and I
would request some help on this.
