earth station with matlab

friends,

i urgently need the methodology of how to realise microwave components like circulator,isolator,..etc..,, using MATLAB.It's urgent...plz...

How detailed do you need to model them?

Dave

just realising them with the normal parameters ...

Well, an Isolator ideally will have no impact on a signal other than about 0.5 to .02 dB of attenuation. Is that the level of modeling that you need to do? The same can be applied to a circulator.

Dave

What kind of medelling you need?
Circuit level? System level? or you need to design the components?

Bye

I need to design them using MATLAB.
(actually how to approach the design?i have no idea....).

Do you mean actually getting into designing the Magnetic components inside the devices, using anisotropic transmission lines? I'd start figuring out how to design them, and then worry about the matlab portion.

Dave

you can design them more effectively by CST.

I agree. Matlab is a very powerful simulation tool for mathematical and theoretical system simulations. For 3D EM simulation you'll need a dedicated simulator like CST or HFSS.

First find out how to design, only afterwards you worry about the tools you have (and most of the time don't have)

I need to design them using MATLAB.

i have some matlab coddes of wilkinson power divider, stepped impedance lpf, lange coupler. imade these as part of my design lab in mtech in last semester. if u need them, i ca give to u. mail me at abhityagi85@gmail.com . for analysing, u have to be familiar with their operation, understand them, and then u can esaily model them accurately. though u will be simulating ideal characteristics as u ant take losses etc, but is a very good method to understand. u can refer to POZAR's book.

Plz send me those codes I need them in my project. my email id is:

Thanks in advance.

i also required the power divider matlab code and mine project is earth station design in c band kindly also mail me the matlab codes and can u simulate that on the ads software or know how to simulate or implement on the ads kindly also guide me in that problem mine email id is island683@sify.com
