ADS Momentum document request about Active circuit

Hi all,
I am a beginner about ADS Momentum,I want to simulate LNA circuit in momentum,i do not know how to begin,anybody kindly share me some examples or links about active circuit how to use the momentum step by step.
Thank you

momentum is an EM simulator , it is valid for passive structures . so u can't simulate the LNA on it

but in ADS there a feature called circuit EM co-simulation, this means that u can draw the layout of LNA and EM simulate it , then convert this momentum to a circuit , and conenct the transistor in the schematic level

Thanks,Khouly.You mean that i have to co-simulate
LNA in schematic,another hand which schematics can simulate in PCB directly?

the layout without the component will be simulated in momentum , then the output of momentum will be feed to the schematic , to take it into simulation

Thanks for your reply.I found a project in ADS example directory(Momemtun/RF/RF board),it also has no components on it,and i do know whether it is usable project in practice.It can be simulated in layout directly, how to feed it to schematic to simulate it?

after u draw the layout , connect in components places ports , then from momentum menu , select component create , then , give it the frequency range and ur done

go to the schematic , and oen the library , select from the library , the layout name and place it in the schematic

I see now,Thanks,Khouly!

And how can i generate ADS momentum file to PADS or Powerpcb?

i don't know about this , which version of PADS and ADS do u use ?

khouly

PADS2005 and PowerPCB5.3

what i am sure about that there is interface between ADS and allegro , but the PowerPCB , don't know ,

but u can export the gerber files from ADS , and import them to PowePCB

wish this helps u

Thanks!
