DBC-1200 Lite_User Manual
Output splitter selector
Referring to the network design documentation, configure the output splitter by installing a 0 pad/attenuator into
the last three of five holes on the right-hand side (to pass all RF into port 1) or the first three holes on the left-hand
side (to pass all RF into port 2). Alternatively, install a relevant 2-way splitter or directional coupler.
Diplexer and diplexer upgrade
Referring to the network design documentation, verify that the diplexer has the correct band split.
Make sure that the output diplexer (right diplexer) has metal screening installed.
Output diplex shielding is required to meet the specified flatness specifications up to 1.2 GHz.
In the initial production of the DBC-1200 Lite the RF shield is glued to the diplexer. In later batches the shield
is held in place by a plastic clip.
The glued diplexer can be removed in the field and re-used on a standard diplexer for a future diplex upgrade.
(Removal of a glued diplexer is described in a separate document).
