Re: RF inductors in OrCad

You are basically using the wrong software for the job. PSpice is a general SPICE simulator, and CAN do RF simulation, but you have to do a lot of the work yourself. What you are needing is an RF specific simulator, that can take a spiral inductor definition and simulate it for various characteristics. For that, you might be better served looking at Microwave Office, or the Agilent tools. If you just need to extract a generic spice model from your spiral, Ansoft has tools that can do that.

But, if you are going to do spiral inductors and other RF design, you are going to need CAD to get it right!

Thanks Charlie. I checked MW Studio and from what I found it is only suitable
for 2d objects and similarly like sonnet (fully 3d tool) which I found fallowing the path
you suggested it doesn't use typical wires but micro strips which I'm not too familiar with
and not sure if I can use them to simulate a macro sized inductor with them. Also I'm not sure
what they mean by ports in both of the programs. Honestly, I thought I could find something
more user friendly for old fashion electrical engineers rather than computer experts.

Welcome to the wonderful world of RF design. The rule is, THERE ARE NO WIRES! 8-) Everything is a transmission line, and there are no 'just connection' wires in your design.
