A klystron is a specialized linear-beam vacuum tube that amplifies low frequencies for communications
A. Yes
B. No
Answer B… A klystron is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power klystrons are used as output tubes in UHF television transmitters, satellite communication, radar transmitters, and to generate the drive power for modern particle accelerators.
