The RF Engineers are the professional experts known within the electrical engineering arena of IT and Telecom sector.
They are also called Radio Frequency Engineer.
Usually, engineers work with gadgets that send or receive radio waves, with wireless devices, radios, and mobile phones.
Basic Principles of Operations
RF system is responsible for the transmission and reception of wireless signals.
RF Transmission: An RF signal is created by upshifting a low bandwidth (DC-like) signal to radio frequency by a radio transmitter.
Radio frequency is produced by oscillating current a specified number of times and then radiating it off a conductor, referred to as an antenna, into empty space (this refers to space occupied by air rather than solid objects and does not refer to outer space) as electromagnetic radio waves.
