AD8347 Down-Conversion Demodulator

AD8347 Down-Conversion Demodulator Description

1. Highly Integrated Design - On-chip integration of AGC, local oscillator drive, DC , and baseband level detection, simplifying peripheral circuitry and miniaturizing the system. Power consumption is only 320mW at a 5V supply, with a typical operating current of 64mA, ensuring energy efficiency and high efficiency.
2. Wide Bandwidth and High Dynamic Range - Supporting inputs from 800MHz to 2.7GHz, it provides a 70dB variable gain range with high linearity between gain and control voltage, making it suitable for wide dynamic range receiver systems.
3. Flexible Interface Configuration - The and LO ports support differential or single-ended inputs, compatible with various LNA and VCO drivers. The baseband outputs support differential or single-ended modes, enabling direct connection to an ADC or other processing circuitry.
4. Excellent Quadrature Performance - Phase error of the I/Q outputs is less than 1, and amplitude imbalance is less than 0.3dB, meeting the requirements for high- dual-channel signal output.
5. Versatile Application - Suitable for cellular base stations, wireless links, satellite modems, test equipment, and other scenarios.
