The K u band (/ ˌ k eɪ ˈ j uː /) is the portion of the electromagnetic spectrum in the microwave range of frequencies from 12 to 18 gigahertz (GHz). The symbol is short for "K-under" (originally German: Kurz-unten), because it is the lower part of the original NATO K band, which was split into three bands (K u, K, and K a) because of the presence of the atmospheric water vapor resonance ...

The IEEE K-band is a portion of the radio spectrum in the microwave range of frequencies from 18 to 27 gigahertz (GHz). The range of frequencies in the center of the K-band between 18 and 26.5 GHz are absorbed by water vapor in the atmosphere due to its resonance peak at 22.24 GHz, 1.35 cm (0.53 in).
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
K band (IEEE), a radio frequency band from 18 to 27 GHz K band (infrared) , an atmospheric transmission window centred on 2.2 μm K band (NATO) , a radio frequency band from 20 to 40 GHz
The NATO K band is the obsolete designation given to the radio frequencies from 20 to 40 GHz (equivalent to wavelengths between 1.5 and 0.75 cm) during the cold war period. Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA). [ 1 ]
Intelsat 14 has a C-band and K u band payload, each of which is further divided to provide service to 2 each coverage areas. [2] The C-band payload has an Americas beam which covers the southern part of the United States, all of Mexico, Central America, and all of South America. A second C-band beam provides coverage for Western Europe and Africa.
