NATO F band[edit]

The NATO F band is the range of radio frequencies from 3 GHz to 4 GHz in the system of letter designations for frequency bands used by NATO for electronic countermeasure (ECM) applications.[1][2] This is equivalent to wave lengths between 10 cm and 7.5 cm. The F band lies at the lower end of the SHF range of the radio spectrum, as defined by the ITU.[3] The NATO F band corresponds to the upper half of the S band (2–4 GHz) of the older IEEE classification system.[4]

Waveguide F band[edit]

The waveguide F band is the range of radio frequencies from 90 GHz to 140 GHz in the electromagnetic spectrum,[5][6] corresponding to the recommended frequency band of operation of WR8 waveguides. These frequencies are equivalent to wave lengths between 3.33 mm and 2.14 mm. The E band is in the EHF range of the radio spectrum.
