Wide gap for a package isn't liked by MGAP2

AB202408227656 over 1 year ago

I need to leave a space in my layout for a 2.2mm wide package so I've tended to use a MGAP2 in between the in & out microstrip. This works fine for EM simulation but for linear analysis it gives a tiresome error

S/H=2.75 must be <1

Is there any way to make it degenerate in the obvious fashion to being no connections in this case? When I remove them to linear simulate my layout gets all messed up!

This model is valid within the following ranges (where H is the substrate thickness):

0.5 < W/H < 2.5

0.1 < S/H < 1

1 < ε_r < 216

Thank you - so I need to use another model. MGAPX works and now I have my first real EM co-simulation results.
