hfss wilkinson
I am modeling a 3dB wilkinson divider at 30 GHz. In ADS, the S parameters and performance is exactly what I would expect. I then export the layout in dxf and import it into HFSS. After adding all the geometries and ports to HFSS the model converges and solves. However, I have run into something that I can't explain. When I run the HFSS model with a lumped RLC (100 ohm) BC the S parameters are all screwy. When I remove the lumped RLC, the S parameters look just like a wilkinson but just a little wider than ADS.\
Any suggestions or comments?
Thanks
