Spaun SBK 5503 NFI 842488 User Manual

The UniSystem multiswitches can be used as stand-alone 
device or can be cascaded with themselves for an easy
extension of the number of subscribers. The UniSystem is
extendable to up to 16 SAT IF levels.

•  After the SAT signal has been decoupled by
 

microstripline directional couplers, it is amplified for  

 

each receiver output, which produces a tap gain 

 

of -4 ... 2 dB. (SMS 5547 UI)

The multiswitch comes with 5 DC-decoupled 
terminating resistors to terminate the 
trunk lines.

1.   As a single multiswitch for 4 SAT IF signals
2.  In „piggyback“ mode in conjunction with a multi- 
 

switch relay extensible for 8, 12 or 16 SAT IF signals.

 

In addition to the wall mounting frame, the 

 

„piggyback“ assembly also includes an adapter frame 

 

in delivery

3.   The master outputs also facilitate cascading, so that  
 

the number of receivers can be increased. Without

 

amplifying the signal, it is possible (depending on  

 

cable quality and length) to feed up to 24 receiver
