Hi, everyone!
when I simulate the conversion gain of mixer, I can choose PXF or PSP. but the result is different. I think the result of PXF is voltage gain, and the result from S21 of PSP is power gain, Is it right?
also, the load of mixer is resistor, when I run the simulation, I add the PORT between the differential output, but how to set the resistor value of the PORT? 50ohm or other values? when I change the resistor value of the PORT, the conversion gain from PXF and S21 are both changed. so, in order to get the right conversion gain result , what value of the resistor in PORT should I set ?
thanks a lot!
