Hi all,
this is my first inquiry at this cool place. Hope to find and give good advice.
I′m simulating cable transformers, baluns and especially power combiners; all with coaxial cables with ferrite cores. The latter doesn′t simulate as soon as the circuit gets more involved.
(for example more than 2 coaxial cables)
I′m simulating the ferrite beads by just placing inductors in parallel with both conductors of each coaxial cable.
Here′s a pdf-file of an amplifier using such coaxial cable transformers with ferrite beads for anybody that′s curious what I mean:

Has anyone done similar or can lead me into the right direction regarding coaxial cable models and it′s limitations? (I′m working in the UHF-range 400M-1G)
I have access to Agilents ADS (2006A) and Orcad′s PSpice.
thanks a heap & keep up the good work
