Eight satellite channels and one terrestrial broadcast channel are routed individually to four users. The channel is selected by analogue signals or by the digital DiSEq Protocol.

Eight satellite channels and one terrestrial broadcast channel are routed individually.
Challenges
A new extended system based on the existing analogue 5/4 switch ASIC was required.
Solution
In a first phase in the context of the EC project (4th Framework) LAP (Large Area panel Processing) a prototype was developed on a thin film substrate on ceramic basis with integrated passive components. This system needed an additional laminate carrier.
Additionally four controller ICs for a digital switching protocol were integrated. In a second step the commercialisation of the system was realised using a Sequential Build Up (SBU) laminate.

Increased functionality and efficiency, together with reduced complexity.
Benefits
Increased functionality and efficiency, together with reduced complexity of the motherboard resulted in a considerable reduction of manufacturing costs, thereby obviating the need for a new ASIC design.
