← TechnologyWhich risk increases when a satellite transponder operates near its intermodulation product threshold?
A)Carrier signal phase modulation
B)Excessive amplifier junction heating
C)Reduced downlink signal clarity✓
D)Antenna feed-line impedance mismatch
💡 Explanation
Reduced downlink signal clarity occurs due to intermodulation distortion; energy spreads among undesired frequencies, interfering with intended signals due to amplifier non-linearity. Therefore, signal clarity decreases, rather than issues of heating or impedance, because the signal is contaminated.
