D) magnetron

Question

Quizplus · Accepted Answer

Bipolar Junction Transistors (BJTs) are preferred for most linear applications because they have a high gain with a low output impedance. This means that they can amplify a signal without introducing significant distortions and maintain a consistent output signal regardless of the load impedance. FETs and vacuum tubes (triodes) are also used, but they are not as commonly used as BJTs due to their higher cost and lower reliability. Magnetrons, on the other hand, are not suitable for linear amplification as they are designed for oscillation and have high output power but poor linearity.
