balun filter

I wanna use 1.6mm FR4 PCB board to design a baluan filter operated at 2.4 GHz band, who can tell me how to design it ?

Thanks.

Hi

Look a this link it could help to start

In this article can find how to design a microstrip balun on FR4 for 2.4GHz.

CMFB is important in such circuit,should be taken great care

in 2.4G,fr4 could be used?
in my kownledge the fr4 usally used lower 2G

I have used FR4 even for C band (3.4GHz). Is not a problem from the moment that you are taken into account the loss.

I use FR4 for 2.4GHz in long time. I believe the majority of 2.4GHz consumer product are using FR4 due to cost. Of course you can't expect too much.

What considerations should I bear if I want to have required response from the filter at higer frequencies say 6,8,12GHz how will FR4 behave there

basically I need specific rejection from the filter at these frequencies and it should have min. insertion loss in the pass band around 2.4Ghz
