AD9864

Overview

The AD98641 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 decimation filter with programmable decimation factor.

  • 10 MHz to 300 MHz input frequency
  • 6.8 kHz to 270 kHz output signal bandwidth
  • 7.5 dB single sideband noise figure (SSB NF)
  • -7.0 dBm input third-order intercept (IIP3)
  • AGC free range up to -34 dBm
  • 12 dB continuous AGC range
  • 16 dB front-end attenuator
  • Baseband I/Q 16-bit (or 24-bit) serial digital output
  • LO and sampling clock synthesizers
  • Programmable decimation factor, output format, AGC, and syn- thesizer settings
