Microwave Frequency Letter Bands

Everytime I see a reference to the "C" band or "Ku" band I can never remember what frequency range these microwave letter bands are refering too.

As a result I've created this handy little cheat sheet, hopefully it will help you as well.

Standard Radar Frequency Letter-Band Nomenclature(IEEE Standard 521-2002)

Band Designator Frequency (GHz) Wavelength in Free Space (centimeters)
HF 0.003 to 0.030 10000 to 1000
VHF 0.030 to 0.300 1000 to 100
UHF 0.300 to 1 100 to 30.0
L band 1 to 2 30.0 to 15.0
S band 2 to 4 15 to 7.5
C band 4 to 8 7.5 to 3.8
X band 8 to 12 3.8 to 2.5
Ku band 12 to 18 2.5 to 1.7
K band 18 to 27 1.7 to 1.1
Ka band 27 to 40 1.1 to 0.75
V band 40 to 75 0.75 to 0.40
W band 75 to 110 0.40 to 0.27
mm 110 to 300 0.27 to 0.10
