AD9864RF/IF射频/中频RFID的射频前端（LNA+PA）规格书PDF中文资料

AD9864属于RF/IF射频/中频RFID的射频前端（LNA+PA）。由亚德诺半导体技术有限公司制造生产的AD9864射频前端（LNA + PA）本系列中的产品是各种集成电路，其中集成了射频 (RF) 信号链连接到系统天线的部分中常见的一种或多种功能，如低噪声放大器 (LNA) 和可编程放大器 (PA)。任何给定器件所含的实际功能各不相同，相比旨在提供更高应用灵活性的器件，针对相对较窄应用的器件通常集成更大一部分必要的信号链。

PRODUCT OVERVIEW

The AD9864 is a general-purpose IF subsystem that digitizes a low level 10 MHz to 300 MHz IF input with a signal bandwidth ranging from 6.8 kHz to 270 kHz. The signal chain of the AD9864 consists of a low noise amplifier (LNA), a mixer, a band-pass Σ-∆ analog-to-digital converter (ADC), and a deci mation filter with programmable decimation factor. An auto matic gain control (AGC) circuit gives the AD9864 12 dB of

continuous gain adjustment. Auxiliary blocks include both clock and LO synthesizers.
