10 Antennas 48 Receivers RF Matrix-Multicoupler rack

 

10 Antennas 48 Receivers RF Matrix-Multicoupler rack

 

Developed for the renovation project of a receiving station of a NATO Navy, the rack  integrates matrix switching and multicoupler functions designed to allow the most flexible use of 10 antennas for association with 48 RF receivers.

In a  43U 19 standard rack the following main components are mounted:

  • qty 1 Power Supply panel for generation of  all the necessary operating voltages 

  • qty 1 Antenna Patch Panel for manual switching between antennas and multicouplers

  • qty 1 RF Matrix  for switching  the multicouplers outputs to receivers # 1 to # 24

  • qty 1 RF Matrix  for switching  of the multicouplers outputs to receivers # 25 to # 48

  • qty 10 Multicouplers, one for each antenna

  • qty 1  Cable terminations panel.

  

Control of the operating functions can be local by keyboard and display or remote over a  RS-232/422 serial line, 9600 bit/sec.

The 10 Antennas 48 Receivers standard configuration can be adapted  for different numbers of antennas and receivers without alteration of the rack layout.

The rack is a compact, lightweight and  self-contained  structure made of aluminum alloys,  removable panels allow easy access to all the internal parts for installation and servicing/ maintenance and troubleshooting  during the operating life.

 

Advanced design and new-generation technologies have resulted in technical characteristics which set performance standards for this type of systems:

  • Frequency range:                           20kHz to 32MHz

  • Input/output VSWR:                      1.4:1 typical

  • Insertion loss:                                0dB nominal

  • Noise figure:                                   < 6dB

  • Decoupling between receivers:   70dB typical if connected to different antennas 35dB typical if connected to the same antenna

  • Decoupling between antennas:   70dB typical

  • Switching time:                             5 msec. max
