D band


NATO D band

The NATO D band is the range of NATO for electronic countermeasure (ECM) applications.[1][2] This is equivalent to wavelengths between 30 cm and 15 cm. It covers the same frequencies as the L band as defined by the IEEE and is a subset of the UHF band as defined by the ITU.[3][4]

Waveguide D band

The waveguide D band is the range of radio frequencies from 110 GHz to 170 GHz in the electromagnetic spectrum,[5][6] corresponding to the recommended frequency band of operation of the WR6 and WR7 waveguides.[7] 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.
