What occurs when the input signal levels to a mixer are too high?
Spurious mixer products are generated✓Bonne réponse
Mixer blanking occurs
Automatic limiting occurs
Excessive AGC voltage levels are generated
Explication
A mixer behaves linearly only up to a level set by its local-oscillator drive and its devices. Beyond that point the higher-order mixing terms grow rapidly, and additional spurious products, including intermodulation between strong signals, appear at the output.
