Other Microwave Bands
The microwave spectrum is usually defined as the electromagnetic spectrum that ranges from 1.0 GHz to 30 GHz in frequency, but some antiquated usages includes lower frequencies. Most common applications are within the 1.0 to 30 GHz range. Microwave frequency bands, as defined by the Radio Society of Great Britain (RSGB), are shown in the table below. Note that frequencies above 30 GHz are typically said to be in the "millimeter wave". because their wavelengths can be conveniently measured in millimeters (mm). The frequency of 30 GHz corresponds quite closely to a wavelength of 10 mm, or 1.0 centimeter.
| L band | 1 to 2 GHz |
| S band | 2 to 4 GHz |
| C band | 4 to 8 GHz |
| X band | 8 to 12 GHz |
| Ku band | 12 to 18 GHz |
| K band | 18 to 26.5 GHz |
| Ka band | 26.5 to 40 GHz |
| Q band | 30 to 50 GHz |
| U band | 40 to 60 GHz |
| V band | 50 to 75 GHz |
| E band | 60 to 90 GHz |
| W band | 75 to 110 GHz |
| F band | 90 to 140 GHz |
| D band | 110 to 170 GHz |
Footnote: "P-band" is sometimes incorrectly used for the Ku-band. "P" for "previous" was a radar band used in the United Kingdom that ranged from 250 to 500 MHz, which is now completely obsolete by the IEEE Standard 521, see and . For other definitions see Letter Designations of Microwave Bands

Famous quotes containing the words microwave and/or bands:
“The New Age? It’s just the old age stuck in a microwave oven for fifteen seconds.”
—James Randi (b. 1928)
“According to the historian, they escaped as by a miracle all roving bands of Indians, and reached their homes in safety, with their trophies, for which the General Court paid them fifty pounds. The family of Hannah Dustan all assembled alive once more, except the infant whose brains were dashed out against the apple tree, and there have been many who in later time have lived to say that they have eaten of the fruit of that apple tree.”
—Henry David Thoreau (1817–1862)
