Rat-race Design
Hi max232
The width will depend on Impedance.
Let us assume I have Rogers substrate, with Er =2.3 & h=31 mil
Usually, for Rat Race, The Input is 50 Ohm so width is 2.2mm
& width of ring will be almost equal to 1.8 mm (impedance 70 Ohm)
They are simple microstrip calculations.

Hi Lupin
If you have ADS, use DG component(template) for Hybrid design.
It will be comparitively much easier.
Also Rate Race can be designed in ADS using template.
