The ADRF6806 is a high dynamic range IQ demodulator with integrated PLL and VCO.
The ADRF6806 IQ demodulator integrates a fractional‑N PLL and VCO to provide a local‑oscillator frequency from 50 MHz to 525 MHz. It offers high quadrature accuracy (<0.5° phase error, <0.1 dB amplitude imbalance) and supports both standard and low‑power modes.
The device is supplied in a 40‑lead, 6 mm × 6 mm LFCSP package, operates from –40 °C to +85 °C, and requires 5 V (VCCBB/VCCRF) and 3.3 V (VCC1/VCC2/VCCLO) supply rails. Detailed specifications, pin descriptions, timing characteristics, and typical performance graphs are provided throughout the sheet.
