7702DA4A-RF & 7703DA4A-RF

40MHz RF 1x4 Active Splitter

Product ManualManual
  • VistaLINK® enabled

The Evertz 7702DA4A-RF / 7703DA4A-RF 1x4 Active Splitters provide amplification and distribution of RF signals from 40MHz to 3GHz. The 7702DA4A-RF / 7703DA4A-RF handle any RF input modulation format and provides 4 isolated outputs for further signal distribution. Typical applications include amplification and distribution of 950MHz - 2150MHz L-Band and 70MHz-140MHz IF signals. Monitoring of RF input power, card status and control gain / attenuation is provided remotely via VistaLINK® capability on the 7703DA4A-RF version. Optional LNB power is available at the input connector on the 7703DA4A-RF version.

The 7702DA4A-RF / 7703DA4A-RF occupy one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
