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

I need a (quick
and dirty) splitter design.
0.1 to 1.0 GHz
5W max input
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?
using an SMT device and mounting it on a PCB, but they're not rated
any higher than 2W.
Any comments will be appreciated.

now from there how do I translate those numbers into
such as: "L" is the inductor, I guess. And the
unit of measure is "m" (meters?)
how do I get that in microHenrys?
Any responses are appreciated!

Well, if you are satisfied with divider's behavior, you can
convert from the electrical parameters into physical parameters, as
Zo=sqrt(Eeff)/(Co*C), where Co is speed of light and C is the capacitance
per unit length. Then calculate the line inductance as L=(Zo^2)*C (inductance
per unit length). Finally, multiply the calculated inductance by the

free rf tool
it has an integrated design tool
calculate all kinds of splitter, divider etc. resistive and wilkinson
anyway its a graet tool to do some simple
simulations in rf
and its free -
but remember your splitter must handle that power
values especially when using resistive splitter
wilkinson design !!
