Launch- and post amplifier for cascading with SMK 99xx F.
SAT IF:
• A special amplifier / filter design improves the
intermodulation properties of the launch amplifiers
considerably
• The high selective input filter guarantees that
• The high selective input filter guarantees that
interference products of the LNBs can not drive the
amplifiers into saturation
• An additional output filter ensures that
intermodulation products and noise effects do not
degrade the terrestrial signal

Forward path:
Terrestrial amplifier with pre emphasis

Return path:
Selectable: off, passive, active
Gain selectable: 20, 15, 10 or 5 dB
• CATV compatible
• Push pull technology
• Level adjuster range: 0 ... -15 dB
• Push pull technology
• Level adjuster range: 0 ... -15 dB
Miscellaneous:
• Selective standby function:
If all subscribers only watch TV programms of SAT system
A, only the appropriate LNB is supplied with power. The
internal logic turns off the power supply of all other LNBs
as well as that of the integrated amplifiers.
This process results in significant energy savings.
