AD8345-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AD8345-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。

PRODUCT DESCRIPTION

The AD8345 is a silicon RFIC quadrature modulator, designed for use from 140 MHz to 1000 MHz. Its excellent phase accuracy and amplitude balance enable the high performance direct modulation of an IF carrier. The AD8345 accurately splits the external LO signal into two

quadrature components through the polyphase phase splitter network. The I and Q LO components are mixed with the baseband I and Q differential input signals. Finally, the outputs

of the two mixers are combined in the output stage to provide a single-ended 50 Ω drive at VOUT.
