mician filter design tool

Microwave filter follows four basic areas:

(1) Synthesis. In this step you can firstly obtain the transmission poles and transmission zeros from the specifications of filter by mathematical theory. Then you get the ideal circuit parameters according to the topology of filter.

(2) Realization. In this step you can get the initial size of microwave structure from the ideal circuit parameters by simulator (HFSS and CST for 3D structure, and Designer and Momentum, IE3D for 2.5D structure).

(3)Tuning. In this step you need to finely tuning the whole filter, escepically the size of every resonator, with the help of simulator.

(4)Fabrication and Measurement.

hi all,
i use ansoft Designer+hfss,
it can use to design Combline filter and intergrated(?) filter

I have been using Mician Wizard and it seems to be quite good

Added after 1 hours 10 minutes:

Hi guys,
I will appreciate if anyone who does have an access to a next door engineering library could post Cristal's paper:

E.G. Cristal ?Capacity Coupling Shortens Combline Filters? Microwaves, Dec 1967, p 44

Thanks!

y can search in this forum and there is a doc paper that y needed

Hi friends,
anyone can tell me what i did wrong in the simulation of an interdigital filter... I folow the steps of results of filter disign program and the results was not the expected.. :D

we use hfss cst and mician for cavity filter design
mician is very good for design

true, I once used Mician for my WG cavity filters at 24 GHz. It 's very good.

Hi, i have just found some points that you may chek on your model in order to get the results you need, I hope this helps you:
1-Integration lines for each port are not defined
2-Make sure when runing simulation the yo have steps enough in order to reach convergence. (As setted 10 steps is not enough)
3-Not certainly sure of this but just in case: you should take care of getting united all the the parts that must be united.

Thanks all, this is really helpful as I am currenty doing a combline filter project. :)
