Name the output wire to the load as Vout and then simulate. After simulation open the result page place the graph and select Vout as output select the type of output ( spectrum in dB, dBm, Smith Chart ot time domain) and thats it. If you know the mixer performance equation we can do a lot more.
I did it , and I got a result I have chosen different frequency based on the diode I selected , RF frequency was 1200 Mhz and LOfreq was 950 Mhz . I want to know how to calculate Conversion gain and loss ?
so , by constructing hybrid or balun can I have a DC bias in subcircuit ? are there some examples for constructing hybrid?

I want to calculate Noise power and Spurious by doing this equation
there is something wrong with this equation ,may you check it out plz
It depends on the power handling capability of the circuit developed and also more importantly your Balun or Hybrid.
Keep in mind whether ur circuit can handle 20 GHz? I think you need a very tight diode model to work at such high frequencies.
