A frequency of 3.5 GHz is categorized in which RF band?

A frequency of 3.5 GHz falls within the Super High Frequency (SHF) band of radio frequencies. The SHF band typically ranges from 3.0 GHz to 30 GHz. This range is often used for radar, satellite communication, and microwave transmission, which aligns with the characteristics of frequencies within this category.

Understanding the classification of RF bands is crucial as it helps in identifying the applications and technologies associated with different frequency ranges. For instance, frequencies below this, categorized as Very High Frequency (VHF) and Ultra High Frequency (UHF), have different uses and characteristics, such as those used in television broadcasting, two-way radios, and mobile communications, but do not extend into the GHz range used for SHF.

The context of other options lies in the fact that High Frequency (HF) typically ranges from 3 MHz to 30 MHz and does not extend into GHz, while Ultra High Frequency is defined from 300 MHz to 3 GHz, meaning they do not encompass the 3.5 GHz frequency either. Thus, it is clear that 3.5 GHz is indeed classified as Super High Frequency, aligning with the recognized RF band standards.
