What is the function of klystron power supply?
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.
What is mean by reflex klystron power supply?
This microwave generator, is a Klystron that works on reflections and oscillations in a single cavity, which has a variable frequency. Reflex Klystron consists of an electron gun, a cathode filament, an anode cavity, and an electrode at the cathode potential. It provides low power and has low efficiency.
What is the range of klystron power supply?

What is klystron and its types?
The klystron amplifier is a device used to amplify microwave frequency signals that reach high stages of power gain by applying the principles of the vacuum tube as well as the electron bunching concept. The UHF region range of klystron amplifier ranges from 300 MHz-3 GHz to 400 GHz.
What is klystron frequency?
These klystrons operate in the frequency range from about 200 MHz (which requires quite large resonators) to the S and X-Bands. large klystrons are used in terrestrial television transmitters in the UHF range.
What is the difference between klystron and magnetron?
It must operate only as oscillator. Magnetron devices are tunable. This means that output frequency can be changed by varying resonant frequency of cavity….Magnetron.
Klystron | Magnetron |
---|---|
It can be used both as amplifier and oscillator. | It can only be used as oscillator. |
What is the use klystron amplifier?
The klystron is a device for amplifying microwave frequency signals that achieve high levels of power gain by applying vacuum tube principles and the concept of “electron bunching”. Klystrons are used in satellite systems, television broadcast, and radar, as well as particle accelerators and medicine.
How does a klystron amplifier work?
Klystron amplifiers amplify the Rf signal. It converts the kinetic energy of the signal in a DC electron beam into the RF power. Inside a vacuum, an electron gun emits a beam of electrons, and the high-voltage electrodes accelerate the electron beam. Then, an input cavity resonator accepts the beam.
What is repeller voltage in klystron?
positive resonator voltage (often referred to as beam voltage) used to accelerate the electrons through the grid gap of the resonant cavity, and. negative repeller voltage used to turn the electron beam back.
What are the applications of klystron?
Applications of Klystron Amplifiers Klystron amplifiers are used in modern systems, they are used from hundreds of MHz (UHF) through hundreds of GHz. These amplifiers can be found in satellite, radar, wideband high-power communication, medicine, high-energy physics.
What is klystron amplifier?
A Klystron (also known as a Klystron Tube or Klystron Amplifier) is a vacuum tube that is used to oscillate and amplify microwave frequency signals. It was invented by American electrical engineers Russell and Sigurd Varian. A klystron uses the kinetic energy of an electron beam.

What is a klystron power supply?
Klystron Power Supply, Model KP-151, is a state-of-the-art solid state, regulated power supply for operating low power Klystrons such as 2K25, 723 A/B, RK 5976, 726, 2K22 etc. Regulated Beam Supply, Repeller and Filament Supply voltages.
What is the power output of a klystrode?
The Klystrode requires a resonant output cavity; in this respect it resembles the klystron. At frequencies much above 1000 MHz, the power output falls off rapidly with increasing frequency, because the device is basically a “density-modulated” or grid-controlled tube limited by electron transit time and grid limitations.
What does klystron stand for?
The name klystron comes from the stem form κλυσ- (klys) of a Greek verb referring to the action of waves breaking against a shore, and the suffix -τρον (“tron”) meaning the place where the action happens.
What is the efficiency of a pulsed klystron?
Because most pulsed klystrons use higher-perveance beams (1.5 to 3 × 10 −6 A/V3/2) to keep the beam voltage low, efficiencies range from 30% to 50%. As much as 11.8% bandwidth has been achieved from a 10-MW klystron with a 1000-ohm “beam impedance.”
