The X band, ranging from 8 to 12.5 GHz (uplink 7.9 to 8.4 GHz, LOF 6.300 GHz), is part of the microwave band of the electromagnetic spectrum. The X band is used by some communications satellites and for radars, primarily for fire control, but also for longer-range ground and weather mapping. It is used primarily, if not solely, by the military. The 3-cm radar spot-band ranges roughly from 5.2 to 10.9 GHz.
The term is also used informally to refer to the extended AM broadcast band.
