ADL5591屬于RF/IF射頻/中頻RFID的RF調(diào)制器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADL5591RF 調(diào)制器射頻 (RF) 調(diào)制器產(chǎn)品用于通過(guò)更改載波的幅度、相位和/或頻率，將信息編碼到正弦載波信號(hào)上。執(zhí)行反向解調(diào)操作的接收設(shè)備會(huì)選擇性地以所需載波頻率接收傳入信號(hào)，從而將載波屬性的變化轉(zhuǎn)換回原始形式。這樣的配置允許使用通信通道來(lái)同時(shí)傳輸多條消息，而彼此之間沒(méi)有干擾。

GENERAL DESCRIPTION

This family of monolithic RF quadrature modulators is designed for use from 869 MHz to 960 MHz and from 1805 MHz to 1990 MHz. Excellent phase accuracy and amplitude balance enable high performance, direct RF modulation for communications systems.
