Features
High dynamic range of amplifi er units
High decoupling between the amplifi er units
Due to the use of a GaAs fi nal stage, the terrestrial
amplifi er is suitable for CATV applications
Adjustable attenuators (in 1-dB steps) for the satellite
range and terrestrial range (the amplifi er branches for
the satellite range and terrestrial range are adjusted
separately)
Adjustable pre-emphasis (steps of 2/4/6 dB) in the
satellite range (each satellite branch is adjusted sepa-
rately) permits optimum pre-emphasis slope in the
cascade
The power supply to the amplifi er units and the LNBs
is provided by an integrated highly effi cient switched-
mode power supply unit
Due to the use of a highly effi cient DC/DC converter,
the power consumption of the VWS 2990 is extremely
low
Suitable for use in Kathrein Sat-IF distribution systems
with 8 x Sat-IF (two satellite positions)
For indoor installation
