Overview
Data Sheet DC to 50 MHz, Quad I/Q Demodulator and Phase Shifter AD8339 FEATURES Quad integrated I/Q demodulator 16 phase select on each output (22.
5° per step) Quadrature demodulation accuracy Phase accuracy: ±1° Amplitude imbalance: ±0.
05 dB Bandwidth 4LO: LF to 200 MHz RF: LF to 50 MHz Baseband: determined by external filtering Output dynamic range: 160 dB/Hz LO drive: >0 dBm (50 Ω), single-ended sine wave Supply: ±5 V Power consumption: 73 mW/channel (290 mW total) Power-down via SPI (each channel and complete chip) APPLICATIONS Medical imaging (CW ultrasound beamforming) Phased array systems Radar Adaptive antennas Communication receivers GENERAL DESCRIPTION The AD83391 is a quad I/Q demodulator configured to be driven by a low noise preamplifier with differential outputs.
It is optimized for the LNA in the AD8332/AD8334/AD8335 family of VGAs.
The part consists of four identical I/Q demodulators with a 4× local oscillator (LO) input that divides the signal and generates th...
