What frequency range does the term "microwave" refer to in radio electronics?

• A. 30MHz - 1GHz
• B. 1GHz - 100GHz
• C. 100GHz - 300GHz
• D. 300MHz - 3GHz

Answer: (B)

The term "microwave" in radio electronics refers to a frequency range that falls between 1GHz and 100GHz. This range is conventionally recognized in various applications, including telecommunications, radar, and cooking, due to the distinct properties of microwaves that allow them to carry information over distances, as well as their ability to heat food through dielectric heating. Microwaves are important in many modern technologies such as satellite communications, wireless data transmission, and microwave ovens. The specified range allows for effective transmission and manipulation of signals and waves, making them ideal for these applications. The understanding of microwave frequencies is essential for technicians and engineers working in related fields, as different components and systems are designed to operate efficiently within this frequency spectrum.
