ADS simulation of Amplifiers

Hi Everyone,

I have a doubt in the simulation of Amplifier

While simulating the matching network for impedance matching, I should neglect the DC path or I should include it.

What kind of role does a DC network play in RF simulation!

Thanks in Advance

DC Biasing or supply circuits are isolated from RF circuit by DC chokes,coupling capacitors etc.
That's why, in an amplifier's simulation DC components are "at the beginning" considered ideal and then in later simulations, equivalent models or s-parameters or large signal models are used to optimize
the amplifier's perfomance.
