  5. 5. ROUTE AMPLIFY SPLIT SWITCH The challenge: ROUTE AMPLIFY SPLIT SWITCH • More and more space crafts orbiting the earth • Bigger and more teleports with many different sizes and designs of antennas
  6. 6. ROUTE AMPLIFY SPLIT SWITCH How RF engineers protect their jobs?
  7. 7. ROUTE AMPLIFY SPLIT SWITCH RF Signal Handling ROUTE AMPLIFY SPLIT SWITCH • GEO orbiting satellites will exceed 420 • Hundreds of LEO and MEO satellites provide interlinks between spacecraft. All eventually beamed down to earth • Increasing traffic density, as well as capacity means broader IF bands (E.G HTS Satellites) • Bigger earth stations and wider range of antennas at each of these teleports • Antennas designed to handle multiple RF links of different frequencies; Ka, Ku and C-bands

  13. 13. ROUTE AMPLIFY SPLIT SWITCH Marine TVRO • Typically 2 or 4 antennas • Typically 4 L-band feeds per antenna (Ku or Ka band) • 16 to 128 receivers (some digiboxes STB’s; and some IRD receivers) • A pair of tracking antennas (e.g. Seatel) with programmed blockage zones for superstructure • Fibre or direct Coax install with LNB powering • Poor isolation and high losses lead to lost signal, especially for Ka band Case Study

  15. 15. ROUTE AMPLIFY SPLIT SWITCH Case Study -Enigma RF Matrix for F1 • 32x32 matrix (expandable) • Fan-out, fan-in, and FIFO options • high resilience applications; custom requirements & asymmetric systems (n>>m) • NEW: NGM-40: 1200-3000 MHz and vari gain; NGM-34: excellent RF specs to 2450 MHz for Ka-band; NGM-35 low noise variant ROUTE AMPLIFY SPLIT SWITCH Benefits & basics: •IF, wideband ,L-band & XL-band options •1 RF card for each RF input & output adding resilience •Hot swap of all active components •Dual redundant CPU’s & PSU’S •On board monitoring & diagnostics

  19. 19. ROUTE AMPLIFY SPLIT SWITCH Signal Redundancy – RF over Fibre Excelling in RF Engineering
  20. 20. Redundant Fibre installation ETL solution & roles: • ETL’s Scorpion passive 2 way splitters are at the front end of each system. 1U chassis holding 4 x 2-ways. • Stingray 1U chassis – each populated with 4 x RX OR TX modules. Total 6 chassis to give redundancy. • 26128 modular system chassis with 2x1 redundancy switches with auto-switchover (total 3 chassis with 4 cards in each). The brief: Etisalat needed 12x 1+1 redundant fibre links for downlink and uplink for some new antennas in Jebel Ali. Requirements included ability to disable (fix) AGC on the uplink & redundant fibre chassis for added resilience.

  22. 22. High performance amplifier ALT-C308 chassis and ALT-R-L1-021 amplifier module ETL solution & roles: • Full RF design • Customisation: new RF module developed to meet the requirements • Supply of amplifiers. • Full FAT report. The brief: develop new 1+1 redundant amplifier to address WGS specifications. 2nd order harmonic <=-63dBc with -10 dBm input; 10-35 dB gain; 1 dB GCP >=29 dBm; gain flatness <=±0.9dB over 1000 Mhz; NF <=20dB at 35 dB gain; 950-2050 MHz.

  24. 24. ROUTE AMPLIFY SPLIT SWITCH ETL Advice • Do ask for advice from the manufacturer – they know whats possible and what has been done by others • Trust in the best you can afford – it will give you peace of mind • Ask for the MTBF and MTTR figures – these show the quality of the components and the quality of the design. • Design for the future – the number and type of satcomms signals continues to grow.
