RF Engineering, also known as Radio Frequency Engineering, is a subset of electrical engineering that deals with devices which are designed to operate in the Radio Frequency spectrum. These devices operate within the range of about 3 Hz up to 300 GHz.

RF Engineering is incorporated into almost everything that transmits or receives a radio wave which includes, but not limited to, Mobile Phones, Radios, WiFi and walkie talkies.

RF Engineering is a highly specialized field. To produce quality results, an in-depth knowledge of Mathematics, Physics and general electronics theory is required. Even with this, the initial design of an RF Circuit usually bears very little resemblance to the final physical circuit produced, as revisions to the design are often required to achieve intended results.


RF Engineers are specialists in their respective field and can take on many different roles, such as design, and maintenance. An RF Engineer at a broadcast facility is responsible for maintenance of the stations high power broadcast transmitters, and associated systems. This includes transmitter site emergency power, remote control, main transmission line and antenna adjustments, microwave radio relay STL/TSL links and more. Typically, transmission equipment is past its expected lifetime, and there is little support available from the manufacturer. Often, creative and collaborative solutions are required. The range of technologies used is vast due to the wide array of frequencies allocated for different radio services, and due to the range in age of equipment. In general, older equipment is easier to service.
