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.

hi...i need to layout a quarter-wave
RF choke which is 600 um length (pretty high frequency operation). However,
I need to bend the microstrip (L shape) to fit it in the area provided
(it's a chip layout). how could i calculate what the physical length
would be for this L shape? i suppose it won't remain 600 um. I've a
EM tool but I don't just want to guess striaghtaway. i don't know much
about microwave so any information will help. also, is it right that
it won't matter what Zo of the line is since i'm just making a RF choke?
