← ScienceWhich consequence results when a microwave amplifier experiences strong reflections back into its input?
A)Spurious oscillation mode is triggered✓
B)Gain compression becomes significantly lower
C)Input impedance reaches near zero
D)Microwave radiation becomes highly polarized
💡 Explanation
A strong reflection induces positive feedback because the reflected wave re-enters the input, fulfilling oscillation conditions; therefore spurious oscillation, rather than gain compression, will occur because energy builds resonantly.
