Greetings: There is so much good stuff on RF Cafe that there is no way to list or
link to all of it here. Please use the Search box or the Site
Map to find what you want - there is a good chance I have it. Thanks!
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.

any idea how to make one, links about concept and
implementation would be nice .

Very simple, take the ad8302 from analog devices,
and you are almost done. Add a directional coupler,
a Rf signal source and thats it. For more details
see the ad8302 datasheet. Maybe u would like
to order the evaluation board...
Post subject: 8302 eval bd

hi all, is there a user group for the ad8302
anywhere ? i bought the eval bd from analog devices
and use it often. and want to visit with other
users the closest thing i have found is a yahoo
group that uses the 8302 with a 9851 dds and
some s/w bw
Unfortunately, the AD8302 method of measuring phase
is not very accurate near the match ( 0 degree and
180 degree). Also, it works best with signals that
are both nearly the same. So you need a lot of ways
to contrive this, and to keep account of attenuators
I am sure it can be useful, especially
in transmitter monitoring and in control loops,
and even to be the heart of a cheaper network analyser,
but I am thinking that real industry network analysers
are unaffordable to guys like me for a reason.
