Radio-frequency identification ( RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits ...

Radio Frequency Systems ( RFS) is a designer and manufacturer of coaxial cable, antenna and tower systems, as well as active and passive RF filters. In 1999, Cablewave, Celwave, and RFS merged worldwide operations and formed Radio Frequency Systems. The company has over 1,800 employees worldwide, operates seven factories (in the United States ...
RF module. An RF module (short for radio-frequency module) is a (usually) small electronic device used to transmit and/or receive radio signals between two devices. In an embedded system it is often desirable to communicate with another device wirelessly. This wireless communication may be accomplished through optical communication or through ...
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 [1] 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, and also ...
Electromagnetism. Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.

Radio over fiber (RoF) or RF over fiber (RFoF) refers to a technology whereby light is modulated by a radio frequency signal and transmitted over an optical fiber link. Main technical advantages of using fiber optical links are lower transmission losses and reduced sensitivity to noise and electromagnetic interference compared to all-electrical signal transmission.
RF Micro Devices (also known as RFMD or RF Micro ), was an American company that designed and manufactured high-performance radio frequency systems and solutions for applications that drive wireless and broadband communications. Headquartered in Greensboro, North Carolina, RFMD traded on the NASDAQ under the symbol RFMD. [3]
