NATO D band
The NATO D band is the obsolete designation given to the radio frequencies from 1 000 to 2 000 MHz (equivalent to wavelengths between 30 and 15 cm) during the cold war period. 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.

Waveguide D band
The waveguide D band is the range of radio frequencies from 110 GHz to 170 GHz in the electromagnetic spectrum,[2][3] corresponding to the recommended frequency band of operation of the WR6 and WR7 waveguides.[4] These frequencies are equivalent to wave lengths between 2.7 mm and 1.8 mm. The D band is in the EHF range of the radio spectrum.
This D-Band lies at the approach to upper frequency limit of contemporary electronic oscillator technology, between 110 and 170 GHz.
