AD8313屬于RF/IF射頻/中頻RFID的射頻檢測器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD8313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 AD8313 is a complete multistage demodulating logarithmic amplifier that can accurately convert an RF signal at its input to an equivalent decibel-scaled value at its dc output. The AD8313 maintains a high degree of log conformance for signal frequencies from 0.1 GHz to 2.5 GHz. Application is straightforward, requiring only a single supply of 2.7 V to 5.5 V and the addition of a suitable input and supply decoupling. Operating on a 3 V supply, its 13.7 mA consumption (for TA = 25°C) is only 41 mW. A power-down feature is provided; the input is taken high to initiate a low current (20 μA) sleep mode, with a threshold at half the supply voltage.

The AD8313 is fabricated on Analog Devices, Inc., advanced 25 GHz silicon bipolar IC process and is available in an 8-lead MSOP package. The operating temperature range is ?40°C to +85°C.
