AT3545G
Full Spectrum DWDM Transmitter
All AT3545G transmitters incorporate a user‐selective (enable / disable) RF input gain stage to permit its use with lower RF input levels.
The AT3545‐xx‐1‐AS series transmitters are designed for “light” analog channel loading (up to 21 8‐MHz analog channels from 85 to 258 MHz) plus QAM channel loading up to 1002 MHz, as well as for QAM‐only full channel loading for digital services in a full spectrum direct feed transmission system or as part of a BC / NC overlay system.
The AT3545‐xx‐2‐AS series transmitters are designed for “full” analog channel loading (up to 64 PAL B / G channels from 85 to 598 MHz) plus QAM channel loading up to 1002 MHz.
As network segmentation increases, each source QAM signal must feed a larger number of QAM transmitters, with resulting RF losses due to the required splitting. Moreover, as each transmitter is able to handle greater numbers of QAM channels, the required combining of the (previously split) individual source QAM signals will also result in higher RF losses. The user‐selectable RF input gain stage provides compensation for these losses.
The unique mid‐plane packaging of the AT3545G features both a compact one‐module‐width design and an integrated “back plate” multiplexer which eliminates the need for a separate platform or shelf for a typically packaged multiplexer. This high density packaging enables network operators to install up to 14 transmitters per 3 RU chassis, all of which can be monitored remotely or locally from the power supply module.
