Multi-switch distribution network amplifi er
The VWS 2500 is used for optimal signal processing on the input of
larger multi-switch cascades, or as cascadable distribution network
amplifi er for compensating cable or tap/splitter transmission losses in
larger distribution networks.
Multi-switch distribution network amplifi ers for the satellite and
terrestrial range in a Kathrein 4 x Sat-IF distribution system
Five amplifi ers (4 x satellite IF and 1 x terrestrial range) in a
single housing
High dynamic range of amplifi er units
High decoupling between the amplifi er units
CATV-capable terrestrial amplifi er unit
Adjustable attenuators (1 dB steps) in each amplifi er unit to
equalise different input levels
Fixed pre-equalisation in the terrestrial amplifi er unit
Adjustable pre-equalisation (2/4/6 dB) in each satellite amplifi er
unit
Low power consumption based on high-effi ciency short-circuit-
proof switch-mode power supply unit
LNB can be remote fed via the horizontal low input.
All other inputs are voltage-free (enabling operation with UAS 485)
For indoor installation
