- 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.
