Encyclopedia > X band

The X band, ranging from 8.0 to 12.0 GHz, is part of the microwave band of the electromagnetic spectrum. The X band is used by some communications satellites and by X-band radar primarily for science and technology applications. The 3-cm radar spot-band ranges roughly from 5.2 to 10.9 GHz. A gigahertz is a billion hertz or a thousand megahertz, a measure of frequency. ... This page is about the radiation; for the appliance, see microwave oven. ... Legend: γ = Gamma rays HX = Hard X-rays SX = Soft X-Rays EUV = Extreme ultraviolet NUV = Near ultraviolet Visible light NIR = Near infrared MIR = Moderate infrared FIR = Far infrared Radio waves: EHF = Extremely high frequency (Microwaves) SHF = Super high frequency (Microwaves) UHF = Ultrahigh frequency VHF = Very high frequency HF = High frequency...
