Radio frequency downconverter
From Wikipedia, the free encyclopedia
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.
