WebJul 28, 2024 · Noise at the image band fLO (+ or -) fIF. Noise at the IF frequency fIF. fRF: In a typical receiver the input to the mixer will have excess noise (above the thermal floor) due to the front end low noise amplifier (LNA). This noise will be downconverted to the IF band with the same conversion loss as our desired RF signal. WebThe LO alternately biases the diodes into the exponential region and the RF rides on top of that wave. The IF is combined through the nonlinear diodes, resulting in a multiplying effect. There's nothing directional about the circuit, so it works as an up or down converter. 6 …
