Hi: everybody
I am trying to simulate and design a matching circuit of PA in ADS environment. The procedure I am following is this
firstly I simulate the schematic using MLIN, Term,MTAPER etc. ( and S2P if needed), also I put MSTEP here and there to cope with the step effect. Being aware of the fact that using MTEE is range limited, I create My own MTEE_MOM in momentum, the schematic is shown below:
then I generated the corresponding layout and simulated using momentum (circuit shown below)
Since I have done a lot of work in generating my schematic to emulate the real layout I expected these two results should match to some degree.simulation results shown below:
they are matched, only in shape, in smith chart, but the reflection result generated by momentum is order of magnitude large than the one from schematic.
So My questions are:
Should these two results match to each other (to some extent) if we carefully prepare our schematic?
if Yes, How can I do to make them match?
if the answer to first question is No, then, how to do matching of filter design? using EM simulation directed? then these ADS microstrip components are worth nothing?
Thanks
