PSPICE: Transmission line / Microstrip components

[Mikal]

Is it possible to simulate microstrip components in pspice? i.e.
quarter wavelenght stubs as bandpass filters... Open ended stub would
be a series resonant short, grounded end would be a parallel resonant
open.

Yes, but RTFM. I have a stripline part placed in my personal library
by a Garmin engineer, back when I was doing GPS chip designs, but I
don't know how it works.

I have a vague memory of them being a problem in TRAN simulations. Something
about the required (small) step size causing very slow simulations. But that
might have been just for Pulse waveforms.

That's true for IDEAL lines. I'm pretty sure that there is a
dissipative model in there as well.
