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
qty 1 Antenna Patch Panel for manual switching between antennas and
qty 1 RF Matrix for switching the multicouplers outputs to receivers # 1 to
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
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
