Radio frequency upconverter

Radio frequency upconverter

A radio frequency upconverter is a device that takes an input of radio frequency energy of a specific frequency range and outputs it on a higher frequency. Likewise, downconverters take an input frequency and reduce it to a lower output frequency. Both converters are commonly used in transverters and satellite communications. Upconverters achieve this frequency conversion via heterodyning, the same principle as modern receivers and transmitters to offset the frequency.
