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 .
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).

Radar-frequency bands according to IEEE standard [17] Band designation Frequency range Explanation of meaning of letters; HF: 0.003 to 0.03 GHz: High frequency [18] VHF: 0.03 to 0.3 GHz: Very high frequency [18] UHF: 0.3 to 1 GHz: Ultra-high frequency [18] L: 1 to 2 GHz: Long wave S: 2 to 4 GHz: Short wave C: 4 to 8 GHz: Compromise between S ...
The AN/MPQ-64 Sentinel is an X-band electronically steered pulse-Doppler 3D radar system used to alert and cue Short Range Air Defense (SHORAD) weapons to the locations of hostile targets approaching their front line forces. It is currently produced by Raytheon Missiles & Defense.
To ensure a better and interference-free usage by other users, military forces, through their corresponding structures, take care for the monitoring of the frequency bands defined for them, cooperating and exchanging data with other governmental institutions authorized for spectrum management and other non-governmental users, to identify and ...
It operated in the military SHF SATCOM frequency band of 7.25 to 8.4 GHz via a geosynchronous satellite, with a data rate of up to 512 kbit/s. The normal manning level for an VSC 501 station was a crew of two and the system could be set up to provide communications within 15 minutes. [8]
The spacecraft is equipped with two solar panels for generate power to its communications payload, which consists of cross-band military X-band, Ka-band transponders, + 10meters solar panels.Propulsion will be provided by an R-4D-15 apogee motor, with four XIPS-25 ion engines for station keeping.
TPY-2 radar in travelling configuration View from the back on a deployed TPY-2 radar. The AN/TPY-2 Surveillance Transportable Radar, also called the Forward Based X-Band Transportable (FBX-T) is a long-range, very high-altitude active digital antenna array [1] [2] X band surveillance radar designed to add a tier to existing missile and air defence systems.
