AD8344-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AD8344-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 AD8344 is a highperformance, broadband activemixer.

It is well suited for demanding receive-channel applications that require wide bandwidth on all ports and very low inter modulation distortion and noise figure.

The AD8344 provides a typical conversiongain of4.5 dB at 890 MHz. The integrated LO driver supports a 50 Ω input impedance witha low LO drive level, helping to minimize external component count.

The single-ended 50Ω roadband RF port allows for easy interfacing to both active devices and passive filters.

The RF input accepts input signals as large as 1.7 V p-p or8.5 dBm (re:50 Ω) at P1dB.
