Satellite telecommunication systems are in continuous evolution, offering various types of interactive services. In order to provide such services in<br/>a cost effective manner, innovative and miniaturized technologies (low weight and volume) are required, allowing for increasing the density of the<br/>satellite payloads, offering new services and thus reducing the cost of the satellite missions.<br/>SATFIT project aims to investigate the possible introduction into the space market of miniaturized and low-mass RF filters and multiplexers in L/S<br/>bands based ondielectric waveguide resonatorsusing an innovative solution for thermal compensation that will make the filters space compatible.<br/>The SATFIT technology will lead to a drastic reduction of the resonator dimensions and weight (up to 50%) while maintain good performancewith<br/>respect to existing technology (heavy waveguide and combline/coaxialfilters).The proposed devices will replace these filters in satellite<br/>transponders operating in L/S band. Preliminary market survey identified TTC&M (Telemetry Tracking Command & Monitoring)as first application<br/>and MSS(Mobile Satellite Services) and Navigation systems (Galileo, GPS) as future ones. The market segment that can be taken, replacing<br/>standard components is potentially 20% of the total market of L/S band filters for space.<br/>According to the preliminary business plan, the entering into the space market of SATFIT products would increase the companyturnover of more<br/>than 30%. Phase 1 of the project is devoted to the study of the technical feasibility, analysis of the critical technical issues and risks, potential<br/>market survey (including the estimation of market share) and the analysis of the technical and economical requirements.Also a business and<br/>strategic plan for next project phases will be performed. RFM will make a deep analysis on possible partners and collaborations, especially for<br/>manufacturing and qualification activities foreseen for project phase 2.
