Microwave｜Glossary

This page is part of the Electrical Glossary for RF and coaxial systems.

Microwaves are a type of electromagnetic wave with frequencies typically ranging from 300 MHz to 300 GHz.

They are part of the radio wave spectrum and are widely used in high-frequency applications such as wireless communication, radar systems, and satellite communication.

Microwaves can travel through the atmosphere and are suitable for transmitting large amounts of data over long distances.

In addition to communication, microwaves are also used in applications such as remote sensing, navigation systems like GPS, and various scientific measurements.

In RF and coaxial systems, microwaves represent high-frequency signals that require specialized components and careful system design.

Coaxial cables used for microwave frequencies must have low loss, precise impedance control, and high shielding performance to maintain signal integrity.

As frequency increases, effects such as attenuation, skin effect, and dielectric loss become more significant.

Connectors and cables are often specified by their maximum operating frequency, with many standard products supporting up to around 18 GHz, while advanced systems extend well beyond this range.

Proper design and component selection are essential to ensure stable transmission and minimize signal degradation in microwave applications.
