AD8333-EVAL开发板套件编程器的射频评估开发套件开发板规格书PDF中文资料

AD8333-EVAL属于开发板套件编程器的射频评估开发套件开发板。由亚德诺半导体技术有限公司制造生产的AD8333-EVAL射频评估和开发套件，开发板本系列中的产品适用于在已知实施环境中，提供能访问射频相关器件的功能或者有助于访问该功能。所含的焦点产品范围从射频信号链元器件（如放大器和检测器）到模块化收发器，以及不直接包含焦点产品的适配器硬件，但此类硬件可供方便地访问用户单独提供的特定射频产品或系列。

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.
