Hi all,
I have an interesting question regarding conversion gain. I have just simulated a single balanced active mixer and I get three different values of conversion gain..Yeah true..its crazy..Its quite obvious that I am doing something wrong and so I need some suggestions from you all.
1. I computed the conversion gain through this expression (gmin*(2/pi)*RL)
2. Performed a transient analysis and compared RF input voltage level and IF output voltage level.
3. Performed a Harmonic analysis with LO power level sweep and plotted the conversion gain across LO power sweep
I get three different values for these different approaches. Could you please guide me with this.
P.S: I also have issues performing Harmonic analysis in ADS beyond a certain value for RL..I am not really sure why that is.I tried re-setting all the convergence parameters though.
