Upconverter with 1+1 redundancy is applied in large earth stations where cost-effective frequency converter solutions are required.
Lightweight, durable and compact design ensures that the upconverter with 1+1 redundancy is effective solution for mobile reporting stations.
Thanks to aluminum chassis and solid modular interior design, the upconverter with 1+1 redundancy can be installed on military targets. Upconverter with 1+1 redundancy have a large MTBF value, which is more than 120,000 hours.
Upconverter with 1+1 redundancy can be used in VSAT stations, SCPC networks, reporting stations of SNG type, DVB-RCS systems and hubs, and any other systems where compact backup systems are needed.
KEY FEATURES:
- Upconverter with 1+1 redundancy includes the separate frequency converter block, detector module, power supply and reference oscillator.
- Upconverter with 1+1 redundancy consists of two frequency converters, which are integrated in the case of 1RU and can be automatically replaced in “hot” mode (1+1 scheme).
- It is possible to replace a separate converter block with spare redundant unit without shutting down the chassis.
- Upconverter with 1+1 redundancy provides automatic (in case of failure of one of the blocks) or manual switching between the blocks of frequency converters.
- Each converter is a completely autonomous device, which is executed as a replacement block.
- Replacement blocks are frequency converters with dual conversion of 70 MHz / 2400 MHz / L.
- It has local control from the front panel, which has LCD, LEDs and buttons.
- Upconverter with 1+1 redundancy provides complete remote control via Ethernet interface connector located on the rear panel.
MAIN FUNCTIONS:
- Provides the signals frequency conversion from the range of 50 – 90 MHz to the L-band (950-2150 MHz) when working in stations of satellite communication and television (L, S, C, X and Ku frequency bands).
- Provides automatic “hot” backup of converter blocks, reference generators and power supply units according to the scheme 1+1.
- Provides automatic switching to the backup unit when one of the blocks is broken.
- Provides the gain factor adjusting either using buttons on the front panel or remotely.
