radio-frequency source
1Radio noise source — A radio noise source is a device that emits radio waves at a certain frequency, used to calibrate radio telescopes such that received data may be compared to a known value, as well as to find the focal point of a telescope soon after construction …
2Radio-frequency identification — (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. Some RFID tags can be read from… …
3Radio frequency heating — is the heating of materials by radio frequency (otherwise called electromagnetic) energy. This can be divided into 3 general categories as below. The term radio frequency is misleading electromagnetic energy of any frequency is absorbed (and… …

6radio frequency interference — (RFI) Noise caused by any source that generates radio waves at the same frequency and along the same path of another radio wave which interferes with radio reception …
7Superconducting Radio Frequency — (SRF) science and technology involves the application of electrical superconductors to radio frequency devices. The ultra low electrical loss of the superconductor yields RF resonators with extremely high quality factors, or Q . For example, it… …
8Digital radio frequency memory — (DRFM) is an electronic method for digitally capturing and retransmitting RF signal. DRFMs are typically used in radar jamming, although applications in cellular communications are becoming more common. Overview A DRFM system is designed to… …
