Multi-switch distribution network amplifi ers
Sat-IF distribution system
Multi-switch distribution network
amplifi ers
Features
High dynamic range of amplifi er units
High decoupling between the amplifi er units
The terrestrial amplifi er is CATV capable due to a GaAs output
stage
Variable attenuator (in 1 dB increments) for the terrestrial
bands and in the SAT-IF range (Sat polarity signals are set
using the one attenuator)
Adjustable pre-equalisation (2/4/6 dB) in the Sat range (all
Sat polarity signals are set using the one attenuator) enables
optimal equalisation of slope in the cascade
The VWS units are powered through remote feeding by
the EXR 2508/2908 multi-switches via Sat signal polarity
horizontal low
Powering can also be carried out through the DC output using
the NCF 18 (does not encompass LNB supply)
All Sat amplifi er units are equipped with a DC bypass. This
allows loop-through of the LNB supply voltage of the EXR
2508/2908 multi-switches.
Extremely low power consumption due to high-effi ciency
DC/DC converter
For indoor installation
