GENERAL DESCRIPTION

The AD8333 is a dual-phase shifter and I/Q demodulator that enables coherent summing and phase alignment of multiple analog data channels. It is the first solid-state device suitable for beamformer circuits, such as those used in high performance medical ultrasound equipment featuring CW Doppler. The RF

inputs interface directly with the outputs of the dual-channel, low noise preamplifiers included in the AD8332.
