wilkinson power divider design
i need to Ads systematic or pcb file.
Hi,
First of all you have wide BW so you must design the splitter from 3 or 4 stages for good performance.
How to do it? When I did it I start it [in ADS] schematics mode and only after I get good results pass to layuot and make Mometum simulation.
If you need some data material or something else talk to me!

This has been requested many times before. I found this topic using the EDAboard search for wilkinson:

Hi,
I also using Eagleware simulation and this simulator have signal control syntesis
him [simulator] could calculate exactly value of the transmision line and resistor value.
If you need that I calculate just give me you details about splitter I mean
and I will send it to you

hi david,
for my university project, i want to design a 2 way wilkinson power splitter. suggestions are that most of its work is in ADS but i m a beginner for ADS,
=> I need the splitter for the LO freq = 20 Ghz.
=> can u suggest some kind of tutorial for the design and layout etc. (i mean from step 0 to step end)
one thing also, i searched on the web and found 2 differet version of wilkinson power divider. 1. lumped elements and 2. distributed. so what makes difference b/w these two designs and which one would be much better lumped or distributed for such high frequency.
last thing, i m worried about the schematics. i dont know how to design all these things in ADS..
Please help me out
for 20G, you should use microstrip to make the wikinson power splitter. It is a hard work, and be careful about the mechanical design.
hey toni,
u mean to say not to apply lumped elements but the distributed component and hence we have to consider T/L length width etc.
my question is what is the reason for selecting microstrip for such a hight frequency, any pros or cons.
Regards
Because 20G wave length is only 15mm.
Hi
The reason that at u freq u must use microstrip (Planar) and not with lumped devices is that impossible to work with lumped devices
for example inductor have one of the parameters that called SRF, if u working above this freq inductor will behave like capacitor...

Why purchase and place discrete components if the circuit function can be implemented with simple layout = no cost?
implementation with simple layout?
how could that be possible.. i am really sorry i did'nt got ur point. can u explain how..
Let me try again: If you can realize the circuit function with a few transmission lines, why would you use expensive SMD components instead?
in Eagle i am not able to find any operation to simulate a schematics. isn't it just like paint OR Ms-Visio. can u explain how to claculate transmission lines and resistor values via EAGLE. where can i figure out this calculator and what things do we need for these type of calculations...
however I have also started working in ADS but since i am new to this tool, it will take long to understand many things.
can any one provide me a general schematic picture for a 2 way power divider (just want to take an idea which components should be used and where to place them exactly), i will calculate the parameters by my self for line width and length etc..
Regards
Cadsoft Eagle and Eagleware Genesys (now Agilent) are different programs.
