Q. The klystron tube used in a klystron amplifier is a type beam amplifier.

  • (A) linear beam
  • (B) crossed field
  • (C) parallel field
  • (D) none of the mentioned
💬 Discuss
✅ Correct Answer: (A) linear beam
Explanation: in klystron amplifier, the electron beam passes through two or more resonant cavities. the first cavity accepts an rf input and modulates the electron beam by bunching it into high density and low density regions.
