SFG of A Source

SFG of a source is shown below:

N.B.  if Γs is 0 (which means the source impedance is Zo or 50Ωs), then

Calculate Power Waves and Generalized S-Parameters

In ADS, build a circuit and set parameters as shown below:

and simulate the circuit in 1GHz single point.


After simulation, add equations to get incident and reflected power wave:

Note, ZG and ZL should be added to the output database (in simulation control component)


The generalized S-Parameters can be readily calculated by S_Param simulation.

To verify the theory of power wave, calculate:



The results are totally in agreement with each other. Thus the power wave theory is verified.
