RF Basics.
• RF stands for Radio Frequency, but it often used in sense of Electromagnetic signals.
• It may be characterized by:
– Frequency
– Amplitude

RF Basics.
• Frequency: the number of times a signal goes through a complete “up and down” cycle in one second of time. It is measured in Hertz.
• Amplitude: the difference between the maximum and the minimum value during one cycle. It is measured in Volts, and it is related with the strength, or power, of the signal.

Radio frequency (RF) is a frequency or rate of oscillation within the range of about 3 Hz to 300 GHz. This range corresponds to frequency of alternating current electrical signals used to produce and detect radio waves.
A frequency that is much higher than the audio frequencies but below the infrared frequencies; usually, above 20KHz.

This range corresponds to frequency of alternating current electrical signals used to produce and detect radio waves. Since most of this range is beyond the vibration rate that most mechanical systems can respond to, RF usually refers to oscillations in electrical circuits.

Radio frequency (abbreviated RF, rf, orr.f.) is a term that refers to alternating current (AC) having characteristics such that, if the current is input to an antenna, an electromagnetic (EM) field is generated suitable for wireless broadcasting and/or communications. These frequencies cover a significant portion of the electromagnetic radiation spectrum, extending from nine kilohertz (9 kHz),the lowest allocated wireless communications frequency (it's within the range of human hearing), to thousands of gigahertz (GHz).

A pretty straightforward and reasonably complete definition of Radio Frequency can be found at http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci214263,00.html

Hi friends! RF is the spectrum of electromagnetic energy between audio and light: 500 KHz to 300 GHz.
