The aim of the study is to design, manufacture and test an EBB (Elegant BreadBoard) of an opto-microwave wideband reconfigurable receiver front-end (OWR-RFE) for future broadband telecom payloads.
A delta development of main critical optical components of the OWR-RFE to meet the overall system level requirements is included.
The overall objective of this activity is at 3 levels:
- to define the best mission / payload for implementing an optical sub-system
- to develop / upgrade the technology for the space use of the critical optical components
- to design, manufacture and test an engineering model of an optical sub-system corresponding to this mission
Define mission/payload architecture showing a real interest (technical and economical) of optical technology versus microwave technology.
Establish new design rules for optical/microwave engineering
Develop hardware with an emerging technology in the space domain
If the optical technology appears as a breaking technology compare to microwave technology, a new family product could be developed at EQM level in order to cope to business segment evolution needs.
The OWR-RFE will provide the following key functions for telecom repeaters:
* photonic multi-LO flexible frequency conversions
* optical flexible routing and switching of signals
* intermediate amplification of the signals
The OWR-RFE consists of 3 main-subsystems :
- Photonic frequency generation Assembly (P-FGA), providing multiple optical Local Oscilators (LO) to frequency converters
- Photonic frequency conversion assembly (P-FCA), providing frequency translation from RF input frequency to wanted RF output frequency
- Photonic Switching and Routing Assembly (P-SRA) , providing Switching and Routing, and also intermediate amplification of the signals
The study is divided in three phases:
Phase 1A: scenario definition, payload level trade-offs between a classical non optical (RF/Digital) implementation and solution involving optics
Phase 1B: Preliminary design of the an Elegant BreadBoard of an opto-microwave wideband reconfigurable receiver front-end (OWR-RFE)
Phase 2: Detailed design of the an Elegant BreadBoard of an opto-microwave wideband reconfigurable receiver front-end (OWR-RFE)
Delta technology development of selected critical optical components.
Phase 3: Development of an Elegant BreadBoard of an opto-microwave wideband reconfigurable receiver front-end (OWR-RFE)
