Hi,
I am simulating a square law mixer and the input to it is RF+LO. What is the best way to combine RF+LO?
Use 2 ports and vcvs to add? But this screws matching since vcvs has high Rin and low Rout. If I put 50 ohm in parallel with port then I get incorrect NF?
Put 2 ports in series? I want to simulate noise figure and matching.
I slightly read about Y factor techniques etc. Have never done practically. I have set LO as large signal for pss and RF as pac 1V. I hope I am doing correct
