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-----

can a wilkinson power divider be used as a combiner and what are the steps to design it in ADS?
any study material would be helpful.

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

I know a ton on this subject and wilkinson is the way you want to go.
Tommorrow i will upload the book i had for my class into this forum so you can see the basics behind calculating the needed values.
I have used ADS a ton and i recomend it. The line calc tool will make your design fly by real quick. If you have any questions feel free to ask

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 (...)

In my design, I'm using the wilkinson divider as a 'junction' for tx or rx path.
Why do you do that? Even with an "ideal" wilkinson divider, you will loose 3dB in TX and 3dB in RX direction. In TX mode, half of the power is lost in the resistor. In RX mode, half of the power is lost because it goes to (...)

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?

hi all...i want to design an equal power divider for wideband there any power divider that can be function well for at least 3 or 6 way power divider for wideband??my frequency range that i want to cover is 1.5GHz until 8GHz... any advice for me to design it?? thank you...

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

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
