DC block suing Transmission lines - 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.
Below are all of the forum threads, including all the responses to the original posts.

Hi guys...I am the same guy asking question about stubs, etc. I have another question and I will appreciate if someone can answer this question for me. I am working at a frequency where I don't have good enough capacitor so I can't use caps for DC block/AC coupling. How do you get DC block using transmission line. Like quarter-wave is AC choke, what's DC block? Thanks

Use an xacto knife and cut the the transmissionline in half. If you want to get fancy you could a interdigital gap or edge or broadside coupled gap.
