Topic: Microwave Engineering
The TWT is sometimes preferred to the magnetron as a radar transmitter output tube because it is
- A. Capable of a larger duty cycle
- B. A more efficient amplifier
- C. More broadband
- D. Less noisy
Answer: C. More broadband
Explanation: Traveling Wave Tubes (TWTs) are non-resonant microwave amplifiers. Because they do not rely on resonant cavities for operation like klystrons or magnetrons, they are capable of operating over a much broader bandwidth.
