calculating physical length for Quarter-wave RF choke - RF Cafe Forums
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.

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? thanks
