How can I obtain an S2P file for the HMC739LP4E VCO to simulate a 24 GHz local oscillator in AWR?

Question

Accepted Answer

A VCO is a 2-port device with a DC input voltage on one port and an output frequency on the other port. S-parameters define the linear relationship between two ports assuming that both ports are in the same domain, such as RF power in and RF power out. Therefore, it does not make sense to talk about S-parameters for a VCO since the input and output domains are different (DC voltage and RF power). In AWR, you should use a VCO model and populate it with data from the datasheet, such as the Fout vs Vin curve, output phase noise, and output power level.
