ADL5502ACBZ-P7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ADL5502ACBZ-P7射頻檢測器射頻檢測器產(chǎn)品是用于測量射頻信號(hào)的集成電路，包括適用于不同用途的許多型號(hào)，例如顯示待測信號(hào)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(hào)輸入、具有對(duì)數(shù)特征的傳遞函數(shù)。

GENERAL DESCRIPTION

The ADL5502 is a mean-responding (true rms) power detector in combination with an envelope detector to accurately determine the crest factor of a modulated signal. It can be used in high frequency receiver and transmitter signal chains from 450 MHz to 6 GHz with envelope bandwidths over 10 MHz. Requiring only a single supply between 2.5 V and 3.3 V, the detector draws less than 3 mA. The input is internally ac-coupled and has a nominal input impedance of 500 Ω.
