Microwave Frequency Bands

Microwave signals are often divided into three categories:
ultra high frequency (UHF) (0.3-3 GHz);
super high frequency (SHF) (3-30 GHz); and
extremely high frequency (EHF) (30-300 GHz).
In addition, microwave frequency bands are designated by specific letters. The designations by the Radio Society of Great Britain are given below.

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

The term “P band” is sometimes used for ultra high frequencies below the L-band. For other definitions, see Letter Designations of Microwave Bands

Lower Microwave frequencies are used for longer links, and regions with higher rain fade. Conversely, Higher frequencies are used for shorter links and regions with lower rain fade.
