| microwave splitter design QUESTION - 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. chukster Post subject: microwave splitter design QUESTION Posted: Wed Apr 23, 2008 8:14 pm Lieutenant Joined: Wed Apr 23, 2008 7:44 pm Posts: 2 Location: Folsom CA I need a (quick and dirty) splitter design. 0.1 to 1.0 GHz 5W max input power, connectorized with BNC. I am thinking of going with a Wilkinson configuration. Is there a quick and easy solution for this? Such as an online Wilkinson calculator? I investigated using an SMT device and mounting it on a PCB, but they're not rated any higher than 2W. Any comments will be appreciated.

And the unit of measure is "m" (meters?) how do I get that in microHenrys? Any responses are appreciated!

Then calculate the line inductance as L=(Zo^2)*C (inductance per unit length). Finally, multiply the calculated inductance by the line length.
