X band frequency WR112 diplexer Diagram

The X band frequency lies between C Band and Ku Band as shown in the figure-1 below. As mentioned in the table, it lies from 8 GHz to 12 GHz in the frequency spectrum with wavelengths between 2.5 centimeters to 3.8 centimeters. It is part of SHF (Super High Frequency) in the EM (Electromagnetic) spectrum.

From 8 to 12 GHz band, 8.175 to 8.4 GHz band of frequencies are allocated for communication applications as outlined below. RF center frequency of about 8.2 GHz is used for the same.

X band frequency WR112 diplexer TX=7.9-9.0Ghz – 30.0Ghz RX=7.145-7.25 Ghz.

X Band Frequency Advantages

Following are the advantages of X Band Frequency over other frequency bands.
1. Rain fading is dominant in radio frequencies above 10 GHz. Hence X Band does not have much interference from rain fading compare to other higher frequency bands such as Ku band and Ka band.
2. It has lower noise and hence it is reliable band for high data and low noise data communications.
3. X band performs better with smaller antennas and can handle higher power.
