The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering , the frequency range of the X band is rather indefinitely set at approximately 7.0–11.2 GHz .
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.
x Band Satellite Communication operates in the part of the X band or Super High Frequency (SHF) spectrum which is designated by the International Telecommunication Union (ITU) for satellite communication, which is those frequencies in the range 7.25 GHz to 7.75 GHz (Space to Earth) and 7.9 GHz to 8.4 GHz (Earth to Space).

The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. The electromagnetic waves in each of these bands have different characteristics, such as how they are ...
The International Telecommunication Union defines frequency allocation as being of "a given frequency band for the purpose of its use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specified conditions". [2] Frequency allocation is also a special term, used in national frequency ...
Interactive Scenario Builder (Builder) is a modeling and simulation, three-dimensional application developed by the Advanced Tactical Environmental Simulation Team (ATEST) at the Naval Research Laboratory (NRL) that aids in understanding radio frequency (RF) and electro-optical/infrared (EO/IR) propagation.
Spectrum analyzers are widely used to measure the frequency response, noise and distortion characteristics of all kinds of radio-frequency (RF) circuitry, by comparing the input and output spectra. For example, in RF mixers, spectrum analyzer is used to find the levels of third order inter-modulation products and conversion loss.
The AM expanded band, or "X-Band" as MW DXers often call it (not to be confused with the range of microwave frequencies), runs from 1610 kHz to 1710 kHz. This is a relatively new portion of the mediumwave broadcast spectrum, with the first two applications for frequencies having been granted in 1997. [ 1 ]
