Magnetron - Electronics Desk
Definition: A magnetron is a device that generates high power electromagnetic wave. It is basically considered as a self-excited microwave oscillator. And is also known as a crossed-field device.
Magnetron Oscillator - Electronics Club Microwave Engineering
In the magnetron oscillator, the magnetic field is perpendicular to the electric field and is therefore called cross-field or M-type. The magnetron was invented by Hull in 1921 and an improved high power magnetron was developed by Randall and Boot around in 1939.
Magnetron - Radartutorial
What is a magnetron? The magnetron is a high-powered vacuum tube that works as a self-excited microwave oscillator. Crossed electron and magnetic fields are used in the magnetron to produce the high-power output required in radar equipment.
Microwave Engineering - Magnetrons - Online Tutorials Library
High peak power oscillations are provided. Useful in radar applications. The Magnetron is called as Cavity Magnetron because the anode is made into resonant cavities and a permanent magnet is used to produce a strong magnetic field, where the action of …
Magnetron, Part 1: Application and operating principles
2019年7月23日 · A: A magnetron is a specialized vacuum tube which does one thing: it is a power oscillator source for frequencies of several hundred MHz to several GHz. Depending on size and other factors, it can produce tens and hundreds of watts to kilowatts.
Magnetron | microwave, radar, vacuum tube | Britannica
Magnetron, diode vacuum tube consisting of a cylindrical (straight wire) cathode and a coaxial anode, between which a dc (direct current) potential creates an electric field. A magnetic field is applied longitudinally by an external magnet. Connected to …
How does the magnetron work? - Physics Network
2023年5月17日 · A magnetic field is applied longitudinally by an external magnet. Connected to a resonant line, it can act as an oscillator. Magnetrons are capable of generating extremely high frequencies and also short bursts of very high power. They are an important source of power in radar systems and in microwave ovens.
Magnetron - an overview | ScienceDirect Topics
In modern usage, the term “magnetron” refers to the magnetron oscillator in which the interaction of the electronic space charge with the resonant system converts direct-current power into alternating-current power, usually at microwave frequencies.
The Microwave Magnetron - ScienceDirect
In this article the author will try to sketch the magnetron art of today, including the present understanding of the mechanism of oscillation in a magnetron, the properties of a magnetron oscillator as compared to other microwave oscillators, and a review of recent contributions to the further development of the magnetron towards meeting the ...
The Magnetron Oscillator - VIAS
The three-slit magnetrons have been used to produce three-phase high frequency currents. The electrons which return toward the filament often bombard it with sufficient energy to raise its temperature appreciably and cause the emission of a larger number of new electrons.
