Basic Principles of Operations
RF Transmission: An RF signal is created by upshifting a low bandwidth (DC-like) signal to radio frequency by a radio transmitter.
RF reception: An RF signal is picked up by the antenna and downshifted to a low bandwidth (DC-like) signal by a radio receiver.
Basic skills and requirements:
RF Engineers must use computer software tools such as ADS, HFSS, Microwave Office, Genesys, and Sonnet to design the components, systems, and antennas that make up a typical receive and transmit system.
Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz).
