Hi
I have to realize a rf splitter 1 to 4 way for signal Zin 50 ohm Zout 50 ohm Fin 800 - 2400MHz. Is it possible to utilize a Wilkinson combiner? Does anyone help me to find document.
Regard.
Wilkinson combiners are narrow band splitters-combiners.For that frequency band, other techniques should be used such as multiple sectioned directional couplers, hybrid couplers, Lange copulers etc.
Do the outputs need to have the same phase? If not you can start with a quadrature such as branchline or coupled line to get two outputs then put another quadrature on each of these outputs.
If you do not mind loss and no isolation, you can use resistive ones.
You not gone beleive but I design this splitter recently,
if you want i will send it to you. Just tell me what you need: capture, simulation (ads), dxf...
Wilkenson dividers can be very broad band. I would build your design as a 1:2 feeding two 1:2 dividers. I would meander the lines so they did not get too long. You willl probably need the 1:2 dividers to be 2 or 3 sections each. The more sections, the more broadband the two output ports isolation will be.
