Title: receiver simulation by hbnoise
Post by Kyle on May 2^nd, 2016, 10:32am

hi everyone,
I'm working on a normal receiver simulation with mixer and VCO. when it comes to the set up of hbnoise for the NF, I dont know what to do with the Reference side-band, "Enter in field".
My LO freq is 100G, RF inpu freq is 120G, should I put "-1 0" ?

Thank you if you know anything about this question.

I think I know the right set up for reference side-band.
I was just trying to do the conversion gain and NF simulation at the same time.
When we do NF simulation with hbnoise, it should be 1 tone rather than two tone.

For the conversion gain simulation, it should be two tone. But for NF simulation, the RF input power doesn't have huge effects on CG or NF if the input power is small enough. It should be one tone, so the only large signal will be the LO, and that will be easy for the set up.

Even if you want to do CG simulation and NF simulation at the same time, you can just make sure the number for RF signal is zero in "enter in field".
For example, RF 100G, LO 120G,
"Enter in field: -1, 0"
-1 is for the LO, 0 is for the RF
