Which risk increases when a microwave amplifier in a satellite communication payload operates near its peak power output?

A)Increased spurious emission bandwidth
B)Reduced antenna gain effectiveness
C)Decreased thermal noise floor
D)Improved amplifier linearity stability

💡 Explanation

Operating near peak power can cause *intermodulation distortion*, because nonlinearity in the amplifier components causes spurious signals beyond the intended bandwidth, therefore increased bandwidth arises, rather than improved linearity or reduced noise in other scenarios.
