Frequency Bands

Commonly used notation for microwave frequency bands:

Table: Frequency Bands

Frequency	Frequency Range	Wave Length (1)
C band	3.95 to 5.80 GHz	79.5 to 51.7 mm
J band	5.85 to 8.20 GHz	51.3 to 36.6 mm
X band	8.20 to 12.4 GHz	36.6 to 24.2 mm
K_u band	12.4 to 18.0 GHz	24.2 to 16.7 mm
K band	18.0 to 26.5 GHz	16.7 to 11.3 mm
K_a band	26.5 to 40.0 GHz	11.3 to 7.5 mm
