PRODUCT DESCRIPTION  

This customer documentation covers the following products: 

 

DEV 2811 

1:8 Distribution Amplifier; 3.2…4.2 GHz; 50 Ohm, SMA (f)

 

 

DEV 2813 

1:16 Distribution Amplifier; 3.2…4.2 GHz; 50 Ohm, SMA (f)

 

 

DEV 2851 

1:8 Distribution Amplifier; 10.95…12.75 GHz; 50 Ohm, SMA (f)

 

 

DEV 2853 

1:16 Distribution Amplifier; 10.95…12.75 GHz; 50 Ohm, SMA (f)

 

All distribution amplifiers are designed in a way, that the signal applied to the 
input port is routed to an amplifier and then split into 8 or 16 output signals.  

All  products  are  delivered  in  a  1 RU  chassis,  are  equipped  with  female 
50 Ohm  SMA  connectors  for  the  input  and  output  ports,  and  provide 
redundant power supplies.

On  the  right  at  the  front  side  of  the  chassis,  three  LEDs  are  located 
signalizing the power supply operating status of the device: 

  "Power Supply 1" LED (1) 

If this green LED is on, the first power supply unit provides a secondary 
voltage feeding the device partially.  

  "Power Supply 2" LED (2) 

If  this  green  LED  is  on,  the  second  power  supply  unit  provides  a 
secondary voltage feeding the device partially.  

  "Failure" LED (3)  

This red LED is on if either the first or the second power supply unit does 
not deliver any secondary voltage. The reason for this can be a defective 
power  supply,  a  defective  primary  protection  fuse,  or  a  missing  primary 
voltage.
