Objective
The TESMI project contributes to solving the problem of cost/performance of microwave signal distribution/combination within subsystems more and more involved in all microwave multi-component assemblies, such as future information/communication systems. The TESMI approach is based on the innovative adaptation of STRIPLINE manufacturing technology applied to pure TEFLON substrate.
TEFLON offers the best electrical loss characteristics, although physically it is a soft material. However, the use of stripline support may compensate for this mechanical problem allowing full advantage to be gained from the enhanced propagation, electrical and shielding properties, whilst still offering cost reduction compared to existing techniques. TESMI will achieve a first adaptation study, a second part test / validation trials and a dissemination/exploitation plan.
Objectives:
The main objective of the TESMI project is to make available in Europe the manufacturing of pure Teflon based stripline for microwave signal distribution / combination within subsystems, in order to optimise cost/performance in all future information and communication systems involving microwave multi-components assemblies. Actually most of them are more and more based rather on solid state than on tube technology. The solid-state amplifier technology is a typical example of the need for combining several power devices to aim at given electrical characteristics. Classical combination techniques are either microstrip structures, which present shielding weakness, or mechanical stripline, which is more expensive and heavy. The TESMI project will allow manufacturers to avoid these two drawbacks of classical techniques by achieving the adaptation of stripline manufacturing technology to pure Teflon .
Work description:
The work is divided in three work packages plus one for project management.
WP1 is dedicated to the project management. This includes the redaction of the results' dissemination plan and the industrial exploitation plan.
In WP 2 the usual stripline manufacturing technology will be adapted to the Teflon substrate. Effectively this one presents dilatations in all the directions of space. During the process, the teflon can flow out of the structure due to pressure and high temperature. In this workpackage PCL will adapt the stripline technology to the thermal and mechanical properties of pure Teflon. At the end of this workpackage, the manufacturing process of the stripline will be mastered by PCL. Airsys will closely work with PCL to build the design rules that meet the requirements of the most representative information/communication equipment.
WP3 is dedicated to the validation of the manufacturing technology. Airsys will design relatively simple test structures (propagation lines, coupled lines, etc), which will be manufactured by PCL. Measurements will be compared to the simulations. Airsys will perform numerous electrical tests, e.g. high and low power applications, thermal behaviour. The technology adjustment will be discussed with PCL.
New test structures will be designed in WP4. This second run will summarise the problems encountered in the first one. Moreover, Airsys will design more complicated passive structures to completely validate the technology. This second run will be realised by PCL and tested by Airsys.
Milestones:
At the end of WP 2 (To+10), a report will be prepared concluding on technology adaptation and defining the design rules (Milestone M1). The first run (WP 3) will give us the first results. Measurements on the test structures of WP3 and their correlation with simulations will be described in the second report at To+14 (Milestone M2). Finally the WP4 report (To + 18) will summarise the results obtained in the 2nd run. The exploitation and dissemination plan and the final report will be delivered at To+18.
