RF upconverters and RF downconverters are used to change the frequency of an RF signal on a large scale. RF upconverters change a radio frequency (RF) signal to a higher frequency. For example, an intermediate frequency (IF) of 70 MHz or 140 MHz can be changed to a frequency in the GHz range. RF downconverters perform the opposite function. Both RF upconverters and RF downconverters are used in networks that need signal conversion, such as cable TV and satellite communications. RF upconverters and RF downconverters can also be used for digital and spread-spectrum communication systems, microwave links, point-to-point microwave systems, private mobile radio, and wireless networks. Block upconverters are used in the commercial and satellite communications sectors. Some block upconverters can change 950 MHz - 1525 MHz signals to 5.85 GHz - 6.425 GHz signals. Other block upconverters can change 950 MHz - 1450 MHz signals to 14.0 GHz - 14.5 GHz signals. Band block upconverters change frequencies from one band in the electromagnetic spectrum to another; for example, from the C band to the Ku band.

Characteristics of RF upconverters and RF downconverters include high-linearity, low local oscillator (LO) leakage, low noise figure, low conversion loss, selectable output frequencies, low phase noise, and flat frequency response. RF upconverters and RF downconverters can fit bench-top chassis or be rack-mounted. Options include low noise block (LNB), solid-state power block (SSPB), and a variety of connector and impedance options. RF frequency changers are available as pressurized units, lightweight airborne units, rack-mounted units, serial or parallel remote communications, and custom configurations.

RF upconverters and RF downconverters meet the communications standards of the communications networks in which they operate. Manufacturers, suppliers, and distributors of RF upconverters and RF downcoverters provide products that meet Intelsat Earth Station Standards (IESS) 308, 309, and 310. Environmental stress screening (ESS) may be used to assure highly reliable service.
