Difference between Momentum Microwave and FEM Simulator

Hello everyone,

I am designing Microstrip BPF at 10 GHz. I need to know which simulator is better for filter design in ADS. Momentum Microwave or FEM Siumlator? Thanks and Best regards,

Hi,

For a planar structure, the MoM (ADS momentum) method is a good one. You gain in time because the matrix to solve is reduce. With FEM, you solve the problem in three dimensions the matrix is more complex. For 3D structure FEM is preferable. I already designed some filters with ADS momentum and the simulation was quite good and fast.

Good work.
