Objectives
The key objectives of the A3M project are:
- The evaluation of heat sink concepts and manufacturing processes for mounting the MMIC
- The evaluation and characterization of MMIC chipsets
- The development and the detailed design of low loss interfaces.
- The accommodation of active and passive RF components to optimize the mechanical envelope
- The detailed design and manufacturing of a prototype Ku-Band Tx amplifier module based on available components with the goal to validate the proposed concept
Challenges
Based on the upcoming market needs the development of innovative core technologies for high integrated transmit and receive modules, especially designed for active antenna applications, are key. In general, the target areas are data applications in the GEO and MEO space segment and LEO mega constellation purposes. Compared to traditional amplifier equipment the key challenges are the request for very compact RF modules with optimized efficiency to minimize the power dissipation within the active antenna. However, the different mission profiles, e.g. GEO vs. LEO mega constellation, provide different performance and cost requirements.
System Architecture
The high level architecture of each amplifier section consists of:
- Housing and RF transition
- Active RF part
The housing and RF transition itself consists of:
- An optimized mechanical structure
- RF interfaces
- Optimized thermal structure
The active RF magazine itself consists of:
- SSPA or LNA RF line-up
- Phase / Gain adjustment via TM/TC
- Phase & gain tracking to comply to array antenna requirements
Mainbus & TM/TC interface
Plan
The project is divided into 5 main work packages:
- WP1000: Program management
- WP2000: Components and Technology
- WP3000: Demonstrator detailed Design
- WP4000: Procurement, Manufacturing, Test
- WP5000: Project Close-Out
The project 4 main milestones are:
MS1: Kick-off Meeting at the beginning of the project (T0 + 0 months)
MS2: Progress Meeting after finalisation of WP3000 (T0 + 4 months)
MS3: PDR after finalisation of WP2000 and WP3000 (T0 + 6 months)
MS4: Final presentation at the end of the project (T0 + 9 months)
Current Status
