RF layout impact simulation

[Leiser]

Hi,

As everybody knows, the simulation doesn´t really math to the real thing in the lab. I am starting to design LNAs up to 2GHz with ADS. When I do the layout in PROTEL I do it adding all my knowledge about the impact it has in RF performance, but lately I have been thinking if there is any tool to be used to do a RF simulation using the final PCB layout. I know in ads for exemple you can put the transmission lines, taps, pcb material etc, but still it doesn´t take into account, I believe, the influence of other tracks for exemple. is there any way to do a PCB layout and then check the S parameters, noise, etc of that layout to assess exactly how it affects the overall performance?

Thanks.

Ansoft might have something getting to that level of modeling.

Also AWR (Applied wave research) has some very powerful simulation tool that consider also the layout.
