ADRF6807 Overview
The ADRF6807 is a high dynamic range IQ demodulator with integrated phase-locked loop (PLL) and voltage controlled oscillator (VCO). The fractional-N PLL/synthesizer generates a frequency in the range of 2.8 GHz to 4.2 GHz. A programmable quadrature divider (divide ratio = 4) divides the output frequency of the VCO down to the required local oscillator (LO) frequency to drive the mixers in quadrature.
