Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz. This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies; these are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves. Different sources specify differen… Web“RF” refers to the use of electromagnetic radiation for transferring information between two circuits that have no direct electrical connection. Time-varying voltages and currents generate electromagnetic energy …
