This article is about the microwave spectrum. 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 term is also used informally to refer to the extended AM broadcast band. The typical local oscillator frequency of an X band LNB is 6300 MHz. X band is used by some communications satellites and for radars systems. The 3-cm radar spot-band ranges roughly from 5.2 to 10.9 GHz. X band radar has a variety of types. Some of these types are continuous-wave, pulsed, single-pole, dual-pole, SAR, or phased array. X band radar has various uses in civil, military and government institutions; in roles such as weather monitoring, air traffic control, maritime vessel traffic
