hfss bondwire

Hi, guys.

I want to simulate interconnetion between microstrip and MMIC pad, and I use two parallel bond wires to connect them, but I don't know how to set up the lumped port for MMIC pad.

Can anybody give me some advice?Anything will be welcome.

Notice that HFSS has two wizards to create bond wires. You can use lumped ports as a starting point.

Their application engineeriing staff is helpful as well. I would start there with questions.

bond pad wire simulation using hfss

Thank you so much, Azulykit.

I have already ask the Ansoft engineering about the the bond wire simulation.

I have use the wizard and also I use a lumped port .The problem is I don't know how to approach the MMIC pad, just use a 50ohm microstrip line to stand for it?

The ansoft stuff suggests to use the lumped port to connect the bond wire directly,no MMIC pad, but the results seem to be wrong.

Do you have any idea about that?

Hello
lumped port seems to be not valid if your working freq up to ~20GHz
Add microstrip part to bonds, use microstrip waveguide port and deembeding to bonds ref plane. You remove calibration error such way
