AD8351ARMRF/IF射频/中频RFID的射频放大器规格书PDF中文资料

AD8351ARM属于RF/IF射频/中频RFID的射频放大器。由亚德诺半导体技术有限公司制造生产的AD8351ARM射频放大器在射频应用中，射频放大器产品可用于信号增益和缓冲。这些产品与通用运算放大器的不同之处在于，它们通常适用于更高的频率，更倾向于提供不可调节的固定增益，并且输入或输出阻抗值符合常用传输线特性阻抗。

GENERAL DESCRIPTION

The AD8351 is a low cost differential amplifier useful in RF and IF applications up to 2.2 GHz. The voltage gain can be set from unity to 26 dB using a single external gain resistor. The AD8351 provides a nominal 150 Ω differential output impedance. The excellent distortion performance and low noise characteristics of this device allow for a wide range of applications.
