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...

4-Wyde divider - 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 am designing the Synthesizer of RF receiver.
Now I found a little trouble when I am trying to obtain 2 samples of
the same RF signal. I was thinking into use a 4-Wyde resistor divider
but the isolation I obtain between signals is very poor.I am using RF
signals between 1500MHz to 2000MHz with levels from 0dBm to -10dBm.
Any good idea to split the same RF signal to 3 different ways with
good isolation between each other?

If you are open to using
discrete divider ICs then you have many option available from Mini-Circuits
I faced a similar situation (however for 6-7 GHz). I
used a resistor power divider from SuSuMu Co limited. Their parts are
available on digikey. However they give an attenuation of 6 dB and you
should have enough amplification to compensate this loss
