AD8345RF/IF射频/中频RFID的RF调制器规格书PDF中文资料

AD8345属于RF/IF射频/中频RFID的RF调制器。由亚德诺半导体技术有限公司制造生产的AD8345RF 调制器射频 (RF) 调制器产品用于通过更改载波的幅度、相位和/或频率，将信息编码到正弦载波信号上。执行反向解调操作的接收设备会选择性地以所需载波频率接收传入信号，从而将载波属性的变化转换回原始形式。这样的配置允许使用通信通道来同时传输多条消息，而彼此之间没有干扰。

PRODUCT DESCRIPTION

The AD8345 is a silicon RFIC quadrature modulator, designed for use from 140 MHz to 1000 MHz. Its excellent phase accuracy and amplitude balance enable the high performance direct modulation of an IF carrier. The AD8345 accurately splits the external LO signal into two

quadrature components through the polyphase phase splitter network. The I and Q LO components are mixed with the baseband I and Q differential input signals. Finally, the outputs

of the two mixers are combined in the output stage to provide a single-ended 50 Ω drive at VOUT.
