The challenge:


• More and more space crafts orbiting the earth

• Bigger and more teleports with many different sizes and

designs of antennas


Importance of Signal Handling


• Ever increasing traffic between space & terrestrial networks

• GEO orbiting satellites well 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

What ETL matrices do

Case Studies & applications

Excelling in RF Engineering


Case Study 1

Rack layout of ETL Modular system with 50 downlink and 50 uplink chains.

system

ETL solution & roles:

• Initial definition of requirements

• Customisation: each RF path has a variable gain amplifier and splitter (combiner on TX) with variable gain per output; based on ETL’s modular system chassis. New RF cards developed.

• Supply of amplifiers, splitters, fan trays, termination panels, and intra-module cables.

• Supply and integration into racks.

The brief: European teleport wanting to balance, equalise & distribute all downlink and uplink traffic with variable gain & slope to compensate cable

losses; and have variable gain on each splitter output to balance signals


Case Study 2

The brief: US government upgrading and expanding L-band switch matrices and need 64x384 with specific RF performance; compact space

and simple cable installation

Vulcan based 64x384 system in comfortable 3 racks

ETL solution & roles:

• Rack layouts and cabling agreed, with particular regard to concerns over total cabling requirements to modems and antennas

• Customisation: cable management and termination panels (standard RF performance)

• Supply of complete system from termination panel in to termination panel out.

• Supply and integration into racks.


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
