What is the name of the thermionic electron tube used to oscillate and amplify microwave frequency signals?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Klystron.
- A klystron is a specialized vacuum tube that functions as an amplifier for high-frequency radio waves, typically in the microwave range.
- It operates by modulating the velocity of a stream of electrons, which is then used to amplify microwave signals.
