Which risk increases when capacitance varies within RF amplifier impedance matching?

A)Standing wave ratio mismatch worsens
B)Transistor biasing current drifts lower
C)Feedback loop destabilization commences sooner
D)Amplifier power consumption becomes minimal

💡 Explanation

Mismatch negatively affects amplifier efficiency and signal fidelity because reactive changes alter the effective impedance terminating the RF transistors involved; the mechanism is destructive Interference, therefore SWR increases drastically rather than performance increasing uniformly throughout the amplifier.
