A signal at 10 GHz falls in which frequency range?

• A. VHF
• B. UHF
• C. SHF
• D. EHF

Answer: (C)

Understanding RF frequency bands helps place where a given frequency sits. The standard ranges are: VHF from about 30 MHz to 300 MHz, UHF from 300 MHz to 3 GHz, SHF from 3 GHz to 30 GHz, and EHF from 30 GHz to 300 GHz. A signal at 10 GHz falls between 3 GHz and 30 GHz, so it lies in the SHF band. This is why 10 GHz is categorized as SHF rather than VHF, UHF, or EHF. SHF is used for microwave communications and radar, which is a helpful way to remember this boundary.
