Which failure ensues when a high-power microwave amplifier operates above its designed frequency, while utilizing a resonant cavity?

💡 Explanation

A higher frequency causes electromagnetic mode separation to degrade because the cavity dimensions become less optimal for the intended mode; therefore, mode competition increases and efficiency drops rather than causing oscillations or breakdown alone under ideal operating voltages.
