T1.3: Advanced POI based SAW filter and disruptive TX/RX active antenna front-end module specifications [M2-M4]

The objective of this task is to consolidate the specifications of S band POI based advanced SAW filters and disruptive TX/RX active antenna module thanks to the trade-offs conducted into T1.1. More precisely the consolidation of the specification is described below:

• Disruptive S band TX/RX active antenna module: The specification will cover the whole module from input LNA and output HPA, input/output SAW filter, coupler/combiner up/down to innovative compact radiating element. Active antenna architecture specification will also be derived since the SAW filter high compactness allows for fully integrated tile antenna architecture.
• S band RX filter: Based on 5G direct connectivity satellite disruptive TX/RX active antenna module specification,
• SAW filter based on advanced topology and technology will be specified with focus on insertion loss into the required bandwidth.
• S band TX filter: Based on 5G direct connectivity satellite disruptive TX/RX active antenna module specification, SAW filter based on advanced topology and technology will be specified with focus on both RF power handling capability and insertion loss into the required bandwidth.

ALT will bring-in its expertise into RF Passive qualification techniques to consolidate environmental specification to be applied to both and S band TX and RX filters. UCL and INC will bring their expertise in the Si handling substrate specifications and performance FoM.
