AD8364RF/IF射频/中频RFID的射频检测器规格书PDF中文资料

AD8364属于RF/IF射频/中频RFID的射频检测器。由亚德诺半导体技术有限公司制造生产的AD8364射频检测器射频检测器产品是用于测量射频信号的集成电路，包括适用于不同用途的许多型号，例如显示待测信号的峰值幅度，而非其平均值或 RMS 幅度。就这些产品探讨的常见主题包括能够测量高频信号输入、具有对数特征的传递函数。

GENERAL DESCRIPTION

The AD8364 is a true rms, responding, dual-channel RF power measurement subsystem for the precise measurement and control of signal power. The flexibility of the AD8364 allows communications systems, such as RF power amplifiers and radio transceiver AGC circuits, to be monitored and controlled with ease. Operating on a single 5 V supply, each channel is fully specified for operation up to 2.7 GHz over a dynamic range of 60 dB. The AD8364 provides accurately scaled, independent, rms outputs of both RF measurement channels. Difference output ports, which measure the difference between the two channels, are also available. The on-chip channel matching makes the rms channel difference outputs extremely stable with temperature and process variations.
