ADL5387RF/IF射频/中频RFID的RF解调器规格书PDF中文资料

ADL5387属于RF/IF射频/中频RFID的RF解调器。由亚德诺半导体技术有限公司制造生产的ADL5387RF 解调器RF 解调器是设计用于从调制波中提取信号的器件，调制波则是通过使用频率、幅度、相位、放大器或位移器而改变的波。

GENERAL DESCRIPTION

The ADL5387 is a broadband quadrature I/Q demodulator that covers an RF/IF input frequency range from 50 MHz to 2 GHz. With a NF = 13.2 dB, IP1dB = 12.7 dBm, and IIP3 = 32 dBm @ 450 MHz, the ADL5387 demodulator offers outstanding dynamic range suitable for the demanding infrastructure direct-conversion requirements. The differential RF/IF inputs provide a well behaved broadband input impedance of 50 Ω and are best driven from a 1:1 balun for optimum performance.
