Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field in the frequency range from around 20 kHz to around 300 GHz.

Radio frequency engineering, or RF engineering, is the study and application of radio waves with the purpose of creating technology and devices that can both receive and send signals using these waves. RF engineering is an important component for those working in aeronautics, telecommunications, military services, commercial radio, television and space-related professions. People use radio waves to communicate on their cell phones, and RF engineers design and implementing the technology that supports 4G and 5G networks.

This is a beginner course in RF engineering that addresses important concepts, components and circuits used in the RF engineering. This course will serve as a basis to move ahead and build upon more advanced concepts in RF engineering and designs.
