Quad I/Q Demodulator And Phase Shifter

GENERAL DESCRIPTION The AD8339 is a Quad I/Q demodulator intended to be driven by a low noise preamplifier with differential outputs; it is optimized for the LNA in the AD8332/4/5 family of VGAs. The part consists of four identical I/Q demodulators with a 4x local oscillator (LO) input that div

DC至50 MHz、四通道I/Q解调器和移相器

AD8339是一款四通道I/Q解调器，配置为由具有差分输出的低噪声前置放大器驱动，并针对AD8332/AD8334/AD8335系列VGA中采用的LNA进行了优化。该器件包含四个完全相同的I/Q解调器并具有4倍本振(LO)输入，可对此信号进行分频并产生驱动混频器所需的内部0°和90°相内部LO。四个I/Q解调器分别采用不同的RF输入，因此彼此完全独立（假定可接受常见LO）。 \n\n AD8339在单个40引脚超紧凑芯片级器件内融合连续波（CW）模拟波束形成（ABF）和I/Q解调功能，因此尤为适合高密度超声扫描仪。在ABF系统中，通过合理的相位对齐和多接收机通道求和，从而实现时域一致 • 四通道集成式I/Q解调器\n• 每个输出具有16种相位选择（步进为22.5°） \n• 正交解调精度\n• 带宽\n4 LO：LF至200 MHz\nRF：LF至50 MHz\n基带：由外部滤波确定;
