This datasheet describes the ADRF6807, a high dynamic range IQ demodulator with an integrated PLL and VCO supporting 700 MHz to 1050 MHz LO frequencies.
The ADRF6807 is a high dynamic range IQ demodulator that integrates a fractional-N PLL and voltage-controlled oscillator (VCO). It supports local oscillator (LO) frequency ranges from 700 MHz to 1,050 MHz and includes features such as input P1dB, input IP3, and noise figure specifications. The device is suitable for applications including QAM/QPSK RF/IF demodulators and cellular W-CDMA/CDMA/CDMA2000 systems.
The document provides detailed technical specifications, timing characteristics, absolute maximum ratings, pin configurations, and application information. It covers the frequency synthesizer/PLL operation, LO quadrature drive, mixer functionality, and bias circuits, along with register programming examples for setting up the device. This manual is written in Chinese.
