How much gain should be used in the RF amplifier stage of a receiver?
Sufficient gain to allow weak signals to overcome noise generated in the first mixer stage
The RF amplifier's gain should be just enough so that its output noise (amplified input noise + RF amp noise) is greater than the noise contributed by the following mixer stage. This optimizes the overall receiver noise figure.
