The RFFC5071A is a highly integrated RF frequency conversion device containing two mixers, a fractional-N synthesizer, and voltage controlled oscillators (VCOs). The mixers are wideband and can operate to 6GHz for both up and down conversion. The synthesizer can provide a maximum local oscillator (LO) frequency of 4.2GHz. This means that the RFFC5071A is ideal for band shift applications, including up to the 5.8GHz ISM band.
