RF Engineering, also known as Radio Frequency Engineering is a field, in particular within electronics, that deals with devices which are design to operate in the Radio Frequency spectrum. These devices operate within the range of about 3 Hz up to 300 GHz.
RF Engineering is renowned to be a very difficult and highly specialized field, to properly 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 alteration to the design is often required to achieve the required results.
RF Engineers are specialists in this 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 transmitter, and associated systems. This includes transmitter site emergency power, HVAC (high voltage alternating current), remote control, main transmission line and antenna, microwave radio 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 quite wide, due to the different frequency bands used for different radio services, and due to the wide range in age of equipment. In general, older equipment is more easily serviceable.
