RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

microwave splitter design QUESTION - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

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 !!
