J band (NATO)

NATO J band

Frequency range	10–20 GHz
Wavelength range	3–1.5 cm
Related bands	X / Ku / K bands (IEEE) SHF (ITU)

The NATO J band is the designation given to the radio frequencies from 10 to 20 GHz (equivalent to wavelengths between 3 and 1.5 cm). Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA).^[1] However, in order to identify military radio spectrum requirements, e.g. for crises management planning, training, Electronic warfare activities, or in military operations, this system is still in use.
