Background story :
I'm designing a 2-way microstrip wilkinson power splitter in CST MWS. After a succesfull design of the basic splitter (S21~-3dB, S11<-20dB over most of the desired bandwidth) I have extended the output lines and added a 90 ° bend to both lines (...)

I am wondering if it is possible (I think should be) to design broadband multisectional wilkinson power divider/combiner with unequal power split. I found many paper about the subject but they treat about multisectional design of equal split dividers or single section unequal split.
Thanks in (...)

I am currently trying to simulate an array of Vivaldi antennas. I work with ADS Momentum. I have finished the elementary antenna design, but I am having problems with the 2-way wilkinson power splitter. I designed and optimized it using Schematic, but when I create the layout and try to simulate it, some of (...)

these are all simple questions.
you should pick up in theroy of microwave solid circuits .
almost general basic books you will find your answers.
you can see some chapters in this book-----

A conservative design for a wilkinson splitter would take into account that in the worst condition, when both ouputs are completely unmatched and with the worst phase, all the power entering the splitter would be dissipated in one resistor.

Your question is not clear. Do you design your own splitter or already have one? What are design details? If you design it you need to use right transmission lines and connectors. For 50 Ohm 2-way splitter you will need two 70.7 Ohm lines and one 50 Ohm line, all about ? of wavelength long. Also it is very (...)

I'm interested in designing a microstrip power combiner to connect two modules to one antenna (only one module will be connected at a time). The idea is to have just one antenna connector on the PCB regardless the module I'm using at the moment. I've been looking wilkinson's power divider and T (...)

I am designing a microstrip balun and plan to do it by using a wilkinson divider to divide the signal into 2 signals with equal amplitude and then a Lange coupler to obtain 90 degree phase shift between the signals. The problem is with this design I am getting S(2,1) and S(3,1) more than -3 dB. What can be done

thank you DDavid
I use this splitter in power amplifying,so I think separating power in 4(or more) way is my aim.
I think I can use ADS,AWR and Ansoft-designer simulate.But,I have some questions ,which software is the most appropriate one toward my project?
whether wilkinson multistage can be used in (...)

Each arm of the wilkinson splitter/combiner has the impedance Z = Zo*1.41, where Zo is the impedance of the ports (e.g. for Zo=50 ohms result Z = 70.7 ohms).
The isolator connected to the output ports guaranties a perfect 50 ohms, and in this way keeping the designed performances of the splitter/combiner (insertion loss and (...)

I'm designing an 4-way wilkinson power divider with flexible structure. After successful optimalisation I would like to simulate change of S-parameters when you're bending the whole structure. The problem is when I'm bending the structure on cylinder the microstrip line partially isn't touhing the substrate. Even healing tools (...)

Thanks. It makes sense now.
Just the last sentence was a bit blurry... What do you mean by: This just means you have to add a little something extra to the 3 dB
You wrote 3dB is no loss, but later you said to add extra to this 3dB. Didn't understand that...
In my design, I'm using the wilkinson divider as a 'junction' for tx or rx path. When it

hi, yes i need output with full freq band,i will use bandpass filter at each wilkinson output to seperate different bands
This design makes no sense to me. Why not use a simple frequency splitter, instead if difficult broadband power splitter followed by band pass filters?

In order to design properly a wilkinson microstrip power combiner/splitter some guidelines should be followed:
1- The thickness of the dielectric material should be chosen so that the 75 ohms microstrip line's width that makes up the wilkinson is rated for the full operating (...)

I should design a 3dB hybrid (splitter or combiner) in frequency approx 50-100MHz. So i cant use microstrip techniques and besides the power in it could be very large (i.e. 300W). Any suggestions about the technique to use?

using your data the thermal resistance of your microstrip transmission line is about 1.1K/W, which implies that when handling 30W the temperature increase will be about 30K. If you are working at normal temperature (eg 20degC) that means that the transmission line will reach about 50degC at the input (and approximately 70degC at the outpu

This does not work as the transformers are less than 90° (for the 50 to 100 ohm transformer, Rhea uses a cascade of 50 and 100 ohm lines, each is 28.13° long for a total length of 56.25°).
Instead, use any of the "Compact wilkinson" designs described in the link below. The "Webb splitter" may be of interest, where a capacitor is used (...)

I assume you just need a simple equal power in phase combiner.
Google for wilkinson combiner and suspended substrate transmission line. There should be plenty of information to help you.
Avago ApccCAD can be used to help you work out the dimensions for the transmission lines. Depending on the performance you need you may need to optimise the desi
