Spaun SBK 5503 NFI 842488 User Manual

•  SMATV systems
•  Star distribution networks

•  Amplifiers have precompensating 4 dB slope
•  The SAT IF amplifier units are equipped with two

 

filters: one at the input and one at the output to  

perform good noise rejection and good out-of-band

 immunity
•  LNB supply voltage selectable (except SBK 5501 NFI)
•  Only SBK 5502 NF: Separate level attenuator
 

for each SAT IF input 

•  Only SBK 5503 NFI: Synchronous level adjuster for

each low- and high-band to adjust different input

 

levels by 0 ... 10 dB

•  Passive return path compatible terrestrial.
•  18 V / 200 mA remote power  
 

for the active cascades (SMK 55xx3 FA)

•  With the integrated variable attenuator too high input

 

levels can be decreased by 0 ... 10 dB in active    

 

 

mode or the stage could be switched into passive  

 

mode (5 ... 862 MHz)

•  Push-Pull-Technology

•  Passive return path (5 ... 65 MHz)
•  CATV compatible forward path in  
 Push-Pull-Technology
•  With the integrated variable attenuator too high input

 

levels can be decreased by 0 ... 10 dB

 
 

 

•  Standby function
•  Ground Clamp

Remote supply for one post amplifier (except SBK 5501 NFI):

•  SBK 5502 NF one NVF 5522 SR
•  SBK 5503 NFI one NVF 5522 SR
