AD9864-EB屬于開發(fā)板套件編程器的射頻評(píng)估開發(fā)套件開發(fā)板。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD9864-EB射頻評(píng)估和開發(fā)套件，開發(fā)板本系列中的產(chǎn)品適用于在已知實(shí)施環(huán)境中，提供能訪問射頻相關(guān)器件的功能或者有助于訪問該功能。所含的焦點(diǎn)產(chǎn)品范圍從射頻信號(hào)鏈元器件（如放大器和檢測器）到模塊化收發(fā)器，以及不直接包含焦點(diǎn)產(chǎn)品的適配器硬件，但此類硬件可供方便地訪問用戶單獨(dú)提供的特定射頻產(chǎn)品或系列。

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.
