Overview
The AD9864BCPZRL, produced by Analog Devices Inc., is a general-purpose Intermediate Frequency (IF) digitizing subsystem. This device is designed to digitize low-level IF signals in the frequency range of 10 MHz to 300 MHz, with a signal bandwidth ranging from 6.8 kHz to 270 kHz. The AD9864BCPZRL integrates a low noise amplifier (LNA), a mixer, a band-pass Σ-∆ analog-to-digital converter (ADC), and a decimation filter, along with automatic gain control (AGC) and synthesizer circuits. This integration makes it an ideal component for various radio communication systems, including multimode narrow-band radios, UHF/VHF receivers, and SATCOM terminals.
