Any thoughts how this can be turned into a S-parameter simulation for the purposes of link budget analysis? I.e. VCO connected to amplifier, coupler (microstrip design from Momentum), then antenna...Know the input match into the VCO, S-parameters for the coupler and the antenna match...so overall should be able to determine the total loss across the components, etc. Correct?
(1) Do you understand what is VCO ?
(2) Do you underestand S-parameter Analysis correctly ?
(3) Do you understand Link Budget Analysis correctly ?
(4) What characteristics of VCO do you want to consider in S-parameter Analysis ?
(5) What characteristics of VCO do you want to consider in Budget Analysis ?

I can't understand what you want to do at all.
What do you want to mean by "Know the input match into the VCO" ?
Describe correctly and in detail.
But I don't think your appilcation requires Voltage Controlled Characteristics of Oscillator.
I think considering of output impedance of VCO in simulation is enough for your application.
Other characteristics of VCO are not required at all for your application.
Again what characteristics of VCO do you want to consider ?
I am trying to build a high-frequency sensor which has a VCO and a subsequent passive/active path consisting of an amplifier, coupler, antenna, etc.
So I need to know the phase noise of the overall system and separately all the component losses in the system (taken together) to make sure the link budget is satisfied...
