4-Wyde divider - 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.

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 and Hittite.
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
