What is the name of the frequency spectrum region from 1000 MHz to 100,000 MHz?

The frequency spectrum region from 1000 MHz to 100,000 MHz is known as the microwave region. Microwaves have frequencies ranging from approximately 1 GHz (or 1000 MHz) to 100 GHz (or 100,000 MHz). This region is characterized by its use in various communication technologies, such as radar, satellite communication, and microwave ovens.

Microwaves have unique properties that set them apart from other parts of the spectrum, including their ability to penetrate certain materials and interact with water molecules, which is why they are effective for heating food. Understanding this frequency range is crucial for aviation electronics technicians as it forms the basis for many radar and communication systems utilized in aviation applications.
