RF (Radio Frequency) and Microwave Engineering is a specialized field within electrical engineering that focuses on the design, construction, and operation of devices that transmit or receive radio waves. RF engineering specifically deals with devices designed to operate within the radio frequency spectrum. This includes a wide range of devices used in communication systems, such as mobile phones, radios, Wi-Fi, walkie-talkies, and digital satellite television.
The distinction between microwave and RF lies in their respective wavelengths, which affects how energy travels and is transmitted to the treated product. Overall, RF and microwave engineering are integral to the functioning of many technologies that rely on radio wave transmission and reception.
