AD8361屬于RF/IF射頻/中頻RFID的射頻檢測器。由亞德諾半導體技術有限公司制造生產(chǎn)的AD8361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 AD8361 is a mean-respondingpower detectorfor use in highfrequencyreceiver and transmitter signal chains,upto 2.5 GHz.Itis veryeasy toapply.Itrequires a single supplyonly between 2.7 V and 5.5 V,a power supplydecouplingcapacitor, and an input couplingcapacitor in most applications. The output is a linear-responding dc voltage with a conversion gain of 7.5 V/V rms. An external filter capacitor can be added to increase the averaging time constant.
