IF Digitizing Subsystem

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 convert

中頻數(shù)字化子系統(tǒng)

AD9864是一款通用中頻子系統(tǒng)，可對信號帶寬范圍為6.8 kHz至270 kHz的低電平10 MHz至300 MHz中頻輸入進行數(shù)字化處理。AD9864的信號鏈包括一個低噪聲放大器(LNA)、一個混頻器、一個帶通Σ-Δ型模數(shù)轉(zhuǎn)換器(ADC)以及一個具有可編程抽取系數(shù)的抽取濾波器。自動增益控制(AGC)電路提供12 dB的連續(xù)增益調(diào)整。輔助模塊包括時鐘和LO頻率合成器。 AD9864的高動態(tài)范圍和帶通Σ-Δ型轉(zhuǎn)換器內(nèi)在的抗混疊功能，使該器件能處理比目標信號強度高達95 dB的阻塞信號。此特性可以降低中頻濾波要求，從而降低無線電的成本，而且還支持不同通道帶寬的多模無線電，使中頻濾波器具 ? 輸入頻率：10 MHz至300 MHz\n\n? 復(fù)合輸出信號帶寬：6.8 kHz至270 kHz\n\n? 單邊帶噪聲系數(shù)（SSB NF）：7.5 dB\n\n? 輸入三階交調(diào)截點(IIP3)：?7.0 dBm \n\n? 無AGC范圍最高達?34 dBm \n\n? 連續(xù)AGC范圍：12 dB \n\n? 前端衰減器：16 dB;
