Distribution network amplifier for satellite and terrestrial range in Kathrein satellite IF distribution system 4 x satellite IF
Five amplifiers (4 x Sat IF and 1 x terrestrial range) are housed in one cabinet
High modulation stability of the amplifier trains
High decoupling between the amplifier trains
BK suitability of the terrestrial amplifier train by GaAs output stage
For indoor installation
Stepwise adjustable attenuation controls (1-dB step) in each amplifier strip for leveling different input levels
Fixed pre-equalization in the terrestrial amplifier train
Stepwise adjustable pre-equalization (2/4/6 dB) in each satellite amplifier train
Low power consumption due to highly efficient, short-circuit-proof switching power supply unit
LNB remote power supply possibility via the input horizontal low. All other inputs are voltage-free (thus operation with UAS 585 possible)
Kathrein Power Saving: In systems that support Kathrein Power Saving (KPS), the LNB supply is switched off as soon as no receiver is in operation.
