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/APG-66 radar is an X-band [1] solid state medium range (up to 80 nautical miles (150 km; 92 mi)) pulse-Doppler planar array radar originally designed by the Westinghouse Electric Corporation (now Northrop Grumman) for use in early generations of the F-16 Fighting Falcon.
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.
USA 272 (U.S.Strat.Com 41879), or Wideband Global SATCOM 8 (WGS F8) (a.k.a Crazy) is a United States military communications satellite operated by the United States Air Force as part of the Wideband Global SATCOM programme. Launched Delta IV in 2016, it was the eighth WGS satellite to reach (target) orbit.
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.
Diagram of AN/SPY-3 vertical electronic pencil beam radar conex projections. X band functionality (8 to 12 GHz frequency range) is optimal for minimizing low-altitude propagation effects, narrow beam width for best tracking accuracy, wide frequency bandwidth for effective target discrimination, and the target illumination for SM-2 and Evolved Sea Sparrow Missiles (ESSM).
The Sea-Based X-band radar (SBX-1) is a floating, self-propelled, mobile active electronically scanned array early-warning radar station designed to operate in high winds and heavy seas. It was developed as part of the United States Department of Defense Missile Defense Agency's (MDA) Ballistic Missile Defense System.
