K-band

satellite frequency bands

Following are the frequency ranges used in satellite communications. See communications satellite, 5G frequency bands and optical bands.

L-band (390 MHz-1.55 GHz)
 GPS satellites, satellite phones,
  misc commsats,
  SETI outer space exploration

 S-band (1.55-5.2 GHz)
 weather satellites, XM/Sirius radio

 C-band (3-7 GHz) (first satellite band)
 misc GEO commsats, cable TV, cellular
  satellite TV (7-10 ft. steerable dishes)
 See  C-band.

 X-band (8-12 GHz)
 misc commsats

 Ku-band (12-18 GHz)
 TV network satellite distribution, misc
  commsats, satellite TV (18" dishes)

 K-band (18-27 GHz)
 short-range applications due to
 high atmospheric attenuation

 Ka-band (26.5-40 GHz)
 misc commsats, radar, satphone backhaul

 V-band (40-75 GHz)
 high capacity, short range

K-band

The band of electromagnetic radiation operating in the frequency range of 20 to 40 GHz, corresponding to a wavelength of 0.59 to 0.30 in (1.5–0.75 cm). Prior to 1962, K-band's operating frequencies ranged from 18 to 27 GHz, corresponding to a wavelength of 0.62 to 0.40 in (1.6–1.1 cm).

By band, the market has been divided into X-Band, K-Band, Ka-Band, and Others (Ku Band).
This huge amount of data will be transmitted by the satellite from its orbit around the L2 Sun-Earth Lagrangian point at a distance of 1.5 million kilometers from the Earth, using its K-band radiofrequency data transmission system.
To detect the details of a cumulonimbus cloud, we need ultra-short wavelength K-band radar, but these are extremely susceptible to attenuation and would pick up all clouds, creating a mess of distracting information on the radar.
Such switched capacitors are employed to develop phase shifters working in K-band (22GHz) frequency range to yield appreciable performance both in terms of electromechanical and RF characterizations.
The array spacing of the K-band antenna is also [lambda]/2, which consisted of 15 antenna units.
This Tx IC family coupled with Anokiwave's K-band SATCOM Rx ICs provide a complete K/Ka-band earth terminal solution enabling auto-alignment of fixed earth terminals and auto pointing for SATCOM on the move applications using GEO satellite space assets.
The small, lightweight, and low power DAA radar will operate at K-band and be capable of rapidly scanning a broad field of view in azimuth and elevation at ranges out to 3km.
A change in the amplitude of the K-band (at 300 ms) was found with increase in the inhibitor, which indicates that hydroxylamine interacted and inhibited at OEC level.
Masatoshi Imanishi, used Subaru Telescope's Infrared Camera and Spectrograph (IRCS) and its adaptive optics system to observe infrared luminous merging galaxies at the infrared K-band (a wavelength of 2.2 micrometers) and L'-band (a wavelength of 3.8 micrometers).
In this paper, the K-band ground-based hyperspectral microwave radiometer (BHU-K80) for water vapor profiling is introduced, which is used to measure the continuous atmospheric radiation spectral power in 18-26 GHz.
