Data Sheet Features 50 MHz to 525 MHz Quadrature Demodulator with Fractional-N PLL and VCO ADRF6806 GENERAL DESCRIPTION The ADRF6806 is a high dynamic range IQ demodulator with integrated PLL and 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 to 80) divides the output frequency of the VCO down to the required local oscillator (LO) frequency to drive the mixers in quadrature. Additionally, an output divider (divide ratio = 4 to 8) generates a divided-down VCO signal for external use. The PLL reference input is supported from 10 MHz to 160 MHz. The phase detector output controls a charge...
