AFE7444 - RF-sampling AFE

Datasheet Summary

Description

The AFE7444 is a quad-channel, wideband, RFsampling analog front end (AFE) based on 14-bit, 9GSPS DACs and 14-bit, 3-GSPS ADCs.

With operation at an RF of up to 6 GHz, this device enables direct RF sampling into the C-band frequency range without the need for additional frequency conversions stages.

  • 1 DSA per channel tunes output power.
  • Four, 14-Bit, 3-GSPS ADCs.
  • Up to 800-MHz signal bandwidth.
  • NSD:.
  • 151 dBFS/Hz.
  • AC performance at fIN = 2.6 GHz,.
  • 3 dBFS.
  • SNR: 55 dBFS.
  • SFDR: 73 dBc HD2 and HD3.
  • SFDR: 91 dBc worst spur.
  • 2 DSA per channel extends dynamic range.
  • RF and digital power detectors.
  • RF frequen.
