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 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.
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.
XTAR, LLC was founded in 2001. It was the first commercial satellite operator to provide services in the X-band frequency range of 7.25-8.4 GHz, a band reserved exclusively for government and military users, though it launched the fleet with no government funding.
The use of X band provides better target resolution than lower frequency bands, for example the L band, though lower frequency bands generally have better performance in detecting targets with a low radar cross section (RCS). The X band frequency and narrow beam width improve differentiation, or “range resolution,” between smaller objects ...
WGS-10 is the latest part of a constellation of highly-capable communications satellites that serve the armed forces of the United States and its allies. It carries Ka-band and X-band transponders with 8.088 gigahertz of bandwidth. In 2019, Boeing received a contract to build an 11th WGS satellite.
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]
Frequency bands in the microwave range are designated by letters. This convention began around World War II with military designations for frequencies used in radar, which was the first application of microwaves. There are several incompatible naming systems for microwave bands, and even within a given system the exact frequency range ...
