High Quality Content by WIKIPEDIA articles! A radio frequency downconverter is a device that takes an input of radio frequency energy of a specific frequency range and outputs it on a lower frequency. Likewise, upconverters take an input frequency and reduce it to a higher output frequency. Both converters are commonly used in transverters and satellite communications. Downconverters achieve this frequency conversion via heterodyning, the same principle as modern receivers and transmitters to offset the frequency.

High Quality Content by WIKIPEDIA articles! A radio frequency downconverter is a device that takes an input of radio frequency energy of a specific frequency range and outputs it on a lower frequency. Likewise, upconverters take an input frequency and reduce it to a higher output frequency. Both converters are commonly used in transverters and satellite communications. Downconverters achieve this frequency conversion via heterodyning, the same principle as modern receivers and transmitters to offset the frequency. Radio frequency (RF) radiation is a subset of electromagnetic radiation with a wavelength of 100 km to 1 mm, which is a frequency of 3 kHz to 300 GHz, respectively. This range of electromagnetic radiation constitutes the radio spectrum and corresponds to the frequency of alternating current electrical signals used to produce and detect radio waves. RF can refer to electromagnetic oscillations in either electrical circuits or radiation through air and space. Like other subsets of electromagnetic radiation, RF travels at the speed of light.
