In alarm devices, the waveguide is affiliated to an antenna. The magnetron is operated with actual abbreviate pulses of activated voltage, consistent in a abbreviate beating of top ability bake activity getting radiated. As in all alarm systems, the radiation reflected off a ambition is analyzed to aftermath a alarm map on a screen.
Several characteristics of the magnetron's ability achievement cabal to accomplish alarm use of the accessory somewhat problematic. The aboriginal of these factors is the magnetron's inherent alternation in its transmitter frequency. This alternation is acclaimed not alone as a abundance about-face from one beating to the next, but aswell a abundance about-face aural an alone transmitted pulse. The additional agency is that the activity of the transmitted beating is advance over a advanced abundance spectrum, which makes all-important its receiver to accept a agnate advanced selectivity. This advanced selectivity permits ambient electrical babble to be accustomed into the receiver, appropriately abashing somewhat the accustomed alarm echoes, thereby abbreviation all-embracing alarm performance. The third factor, depending on application, is the radiation hazard acquired by the use of top ability electromagnetic radiation. In some applications, for archetype a abyssal alarm army on a recreational vessel, a alarm with a magnetron achievement of 2 to 4 application is generally begin army actual abreast an breadth active by aggregation or passengers. In applied use, these factors accept been overcome, or alone accepted, and there are today bags of magnetron aerodynamics and abyssal alarm units in service. Recent advances in aerodynamics acclimate abstention alarm and in abyssal alarm accept auspiciously implemented semiconductor transmitters that annihilate the magnetron entirely.
edit Heating
In bake ovens, the waveguide leads to a radio frequency-transparent anchorage into the affable chamber.
edit Lighting
In microwave-excited lighting systems, such as a sulfur lamp, a magnetron provides the bake acreage that is anesthetized through a waveguide to the lighting atrium absolute the light-emitting actuality (e.g., sulfur, metal halides, etc.)
