Spaun SBK 5503 NFI 842488 User Manual

•  A special amplifier / filter design improves the  
 

intermodulation properties of the multiswitch  

 considerably
•  The high selective input filter guarantees that

interference products of the LNBs cannot drive the

 

amplifiers into saturation

•  LNB supply voltage selctable. Twin-, SMATV- and

universal twin LNBs can be connected

•  The multiswitches support a standby mode. The  

SAT IF amplifiers and the LNB remote voltage are

 

only active when at least one receiver sends a  

 

voltage to its multiswitch outlet 

•  Amplifier has precompensating > 5 dB slope

The mulitswitches are return path compatible.
•  Push-pull technology
•  With the integrated variable attenuator active or
 

passive distribution can be selected. In active mode  

 

too high input levels can be decreased by 0...10 dB

•  Turned to max. attenuation the amplifier is bypassed
 

and turned off. The passive distribution is return    

path compatible (5 ... 862 MHz)

•  Energy saving switch-mode power supply;
 

short circuit proof 

•  Standby function
•  Groud Clamp
