This article is about the microwave spectrum. For the band called X, see X (band)

For the Super Nintendo and Sega Genesis online adapter, see XBAND

The X band, ranging from 7 to 12.5 GHz (the 10.7-12.5 portion overlapping Ku band), with a standard downlink band of 7.25 to 7.75 GHz (uplink 7.9 to 8.4 GHz), is part of the microwave band of the electromagnetic spectrum. The typical Local Oscillation Frequency of an X-band LNB is 6300 MHz. 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.
