The 3-centimeter or 10 GHz band is a portion of the SHF (microwave) radio spectrum internationally allocated to amateur radio and amateur satellite use on a secondary basis. The amateur radio band is between 10.00 GHz and 10.50 GHz, and the amateur satellite band is between 10.45 GHz and 10.50 GHz. The allocations are the same in all three ITU regions.[1]

Some administrations have authorized spectrum for amateur use in this region; others have declined to regulate frequencies above 300GHz.

All allocations are subject to variation by country. For simplicity, only common allocations found internationally are listed. See a band's article for specifics.
This is not mentioned in the ITU's Table of Frequency Allocations, but many individual administrations have commonly adopted this allocation under "Article4.4".

This includes a currently active footnote allocation mentioned in the ITU's Table of Frequency Allocations. These allocations may only apply to a group of countries.
