The ADRF6807 is a high dynamic range IQ demodulator with integrated phase-locked loop (PLL) and voltage controlled oscillator (VCO). It has a LO frequency range of 700 MHz to 1050 MHz and offers low input power and high linearity performance. It is suitable for applications such as QAM/QPSK RF/IF demodulators, cellular W-CDMA/CDMA/CDMA2000, microwave point-to-(multi)point radios, and broadband wireless and WiMAX.
The ADRF6807 quadrature demodulator integrates a fractional‑N PLL and VCO to provide a local‑oscillator range of 700 MHz to 1050 MHz. It offers high input linearity, low noise figure, and precise quadrature accuracy, making it suitable for QAM/QPSK demodulation, cellular, microwave and WiMAX applications.
The device is supplied in a 40‑lead LFCSP package, operates from 3.3 V and 5 V supplies, and supports SPI programming for PLL configuration. Detailed specifications, pin descriptions, timing characteristics, and typical performance graphs are provided in the data sheet.
