← ScienceWhich outcome occurs when RF signal source impedance mismatches?
A)Reflected wave power increases loss✓
B)Amplifier stability critically improves quickly
C)Signal bandwidth is maintained completely
D)Optimal noise figure is easily obtained
💡 Explanation
Increased reflected power at impedance mismatches wastes power because a standing wave is created, which wastes forward power via dissipative losses, it is therefore the correct answer; rather than optimal gain, which demands good impedance matching.
