Problem with transmission line and SpectreRF Cadence

[Bob WU]

It seems that SpectreRF PSS does not work with ideal transmission line
model from Analoglib, tline. It gives a warning about unable to deal
with distributed components. Actual transmission line component works
fine with PSS.

Is there anyway to use these ideal tline models with PSS simulation?
Or is there some better procedure to design RF matching network?

Thanks!

Hi Bob,

I didn't happen to use PSS with ideal TL I'm afraid.
Just wanted to say that there is an entire chapter in the spectreRF
doc about transmission lines. It might give some hints. have you tried
it ?

Cheers,
Riad.

What version are you using? If using anything from IC5141 onwards, you should be
able to use mtline (which is more advanced than tline - tline is pretty much
useless for most real applications) with PSS.
