The AD8339 is a DC to 50MHz quad integrated I/Q demodulator and phase shifter with 16 phase select on each output (22.5° per step) and quadrature demodulation accuracy of phase accuracy: ±1° amplitude imbalance: ±0.05 dB. It is suitable for applications such as medical imaging (CW ultrasound beamforming), phased array systems, radar, adaptive antennas and communication receivers.
The AD8339 is a quad I/Q demodulator with integrated phase‑shifter. It provides 16 selectable 22.5° phase steps per channel, 160 dB/Hz dynamic range, and operates from a single +5 V supply while consuming 73 mW per channel. The device includes an SPI‑compatible serial interface for programming and power‑down control.
Typical applications include medical imaging (ultrasound beamforming), phased‑array radar, adaptive antennas, and communication receivers. The part is offered in a 6 mm × 6 mm, 40‑lead LFCSP package and is rated for –40 °C to +85 °C operation.
