Which consequence results when rapidly switching a capacitive load powered by an RF amplifier?

A)Transistor overheating risk increases rapidly
B)Improved amplifier impedance matching occurs
C)Harmonic frequency generation suppresses itself
D)Reduced amplifier power supply ripple achieved

💡 Explanation

Transistor overheating risk increases because rapid switching causes large current spikes through parasitic inductance, resulting in ringing via LC oscillation. Therefore, device breakdown is promoted, rather than impedance matching, which is frequency dependent.
