Dear All :
I design a LNA now , the band is 70M ~ 120M , I usae spectre do simulation.
I Run SP , PSS+ Pnoise. I have some question about the simulation. I use Vport or Vsource fot input / ouput. My question is input is 50 ohm. How to define the ouput impedance ? The Next stage is Mixer. I read some document , it apply ouput impedance is 50 ohm. Is it correct ? Thanks.
