AD8364屬于RF/IF射頻/中頻RFID的射頻檢測器。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的AD8364射頻檢測器射頻檢測器產(chǎn)品是用于測量射頻信號的集成電路，包括適用于不同用途的許多型號，例如顯示待測信號的峰值幅度，而非其平均值或 RMS 幅度。就這些產(chǎn)品探討的常見主題包括能夠測量高頻信號輸入、具有對數(shù)特征的傳遞函數(shù)。

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.
