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. Radiofrekvens (RF) är den frekvens (svängningshastighet) som motsvarar radiovågornas, området från cirka 3 kHz till 300 GHz. Växelström i detta frekvensband kan bära radiosignaler. RF avser vanligtvis elektriska snarare än mekaniska svängningar, även om mekaniska RF-system existerar, till exempel mekaniska filter och RF- MEMS The radio spectrum is the part of the electromagnetic spectrum with frequencies from 30 Hz to 300 GHz. Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication Radio frequency refers to an alternating electrical current with certain properties that allow it to be broadcast from an antenna. If the current generates an electromagnetic field or wave at a frequency that is suitable for broadcasting television or radio signals, then it is considered a radio frequency

Radio är trådlös överföring av signaler genom modulering av elektromagnetiska vågor med frekvenser lägre än det synliga ljusets.. Utsändning av radio sker vanligtvis från en sändare som sprider signalerna jämnt åt alla håll och där mottagning kan ske inom det område som täcks av radiovågorna. Området kan utökas med hjälp av reläsändare (slavsändare) som fångar upp. Frequenzen für die Radio-Übertragung Auf der ganzen Welt werden UKW-Stationen im Bereich zwischen 87,5 MHz und 108,0 MHz des VHF-Band II betrieben.

Other articles where Radio-frequency spectrum is discussed: telecommunications media: The radio-frequency spectrum: Before 1930 the radio spectrum above 30 megahertz was virtually empty of man-made signals. Today, civilian radio signals populate the radio spectrum in eight frequency bands, ranging from very low frequency (VLF), starting at 3 kilohertz, and extending to extremely high frequency. (RF) Radio frequency refers to that portion of the electromagnetic spectrum in which electromagnetic waves can be generated by alternating current fed to an antenna. The RF pulses used in MRI are commonly in the 1-100 megahertz range, and their effect upon a body is potential heating of tissues and foreign bodies, such as metallic implants, mainly at the surface Radio Frequency Identification (RFID) is a type of passive wireless technology that allows for tracking or matching of an item or individual.

It is clear that Dr Fornetti has gone to great lengths to remove the bafflement often experienced by people learning about radio frequency and microwave engineering for the first time. In the text Dr Fornetti often poses questions which typical readers might well ask themselves, and goes on to provide clear explanations, often making clever use of analogies, as well as using clear illustrations The term Radio frequency refers to electromagnetic radiation in the range of frequencies lower than microwaves. Radio waves at these frequencies have been found useful for long-range communications. Among these frequencies, shortwave radio communications operate at frequencies that can be reflected by the ionosphere and therefore can bounce around the earth What is an RF Device? The FCC regulates radio frequency (RF) devices contained in electronic-electrical products that are capable of emitting radio frequency energy by radiation, conduction, or other means. These products have the potential to cause interference to radio services operating in the radio frequency range of 9 kHz to 3000 GHz
