AD831RF/IF射頻/中頻RFID的RF功率控制器IC規(guī)格書PDF中文資料

AD831屬于RF/IF射頻/中頻RFID的RF功率控制器IC。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD831RF 功率控制器 ICRF 功率控制 IC 器件可用于測量正在發(fā)射的信號的射頻功率，并向可編程放大器或類似設(shè)備提供相應(yīng)反饋信號，以保持所需的發(fā)射信號功率水平。

PRODUCT DESCRIPTION

The AD831 is a low distortion, wide dynamic range, monolithic mixer for use in such applications as RF to IF downconversion in HF and VHF receivers, the second mixer in DMR base stations, direct-to-baseband conversion, quadrature modulation and demodulation, and doppler shift detection in ultrasound imaging applications. The mixer includes an LO driver and a low noise output amplifier and provides both user-programmable power consumption and third order intercept point.
