Microwave frequency bands

The bake spectrum is usually authentic as electromagnetic activity alignment from about 1 GHz to 100 GHz in frequency, but earlier acceptance includes lower frequencies. Most accepted applications are aural the 1 to 40 GHz range. One set of bake abundance bands designations by the Radio Society of Great Britain (RSGB), is archival below:

L bandage 1 to 2 GHz

S bandage 2 to 4 GHz

C bandage 4 to 8 GHz

X bandage 8 to 12 GHz

Ku bandage 12 to 18 GHz

K bandage 18 to 26.5 GHz

Ka bandage 26.5 to 40 GHz

Q bandage 33 to 50 GHz

U bandage 40 to 60 GHz

V bandage 50 to 75 GHz

E bandage 60 to 90 GHz

W bandage 75 to 110 GHz

F bandage 90 to 140 GHz

D bandage 110 to 170 GHz

P bandage is sometimes acclimated for Ku Band. "P" for "previous" was a alarm bandage acclimated in the UK alignment from 250 to 500 MHz and now anachronistic per IEEE Std 521, see 9 and.10 For added definitions see Letter Designations of Bake Bands.

When radars were aboriginal developed at K bandage during World War II, it was not accomplished that there was a adjacent assimilation bandage (due to baptize breath and oxygen at the atmosphere). To abstain this problem, the aboriginal K bandage was breach into a lower band, Ku, and high band, Ka see.11
