Within a satellite transponder, which mechanism creates intermodulation signal distortion when multiple carriers are amplified simultaneously?

💡 Explanation

Non-linearities within the transponder's amplifier cause intermodulation because different carrier frequencies mix like harmonics. Therefore, distortion products arise degrading signal quality, rather than phase noise, guard bands or antenna alignment being the cause of this intermodulation effect.
