← TechnologyWhich performance degradation results when intermodulation products overload an antenna?
A)Reduced receiver blocking immunity✓
B)Increased signal-to-noise ratio
C)Enhanced frequency selectivity
D)Improved transmission power efficiency
💡 Explanation
Exceeding the linearity range introduces unwanted signals via *intermodulation distortion*, causing spurious signals to interfere because the amplifier's *gain compression* reduces sensitivity to the desired signal. This decreases receiver blocking immunity, rather than increasing selectivity or improving SNR.
