Spaun SBK 5503 NFI 842488 User Manual

•  A special amplifier / filter design improves the

 

intermodulation properties of the launch amplifiers

 considerably
•  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

Terrestrial:
 
•

 

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
 

•  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.
