Interoperability testing with ST Engineering iDirect’s wideband patented MCM7500 Multi-Carrier Modulator and EASii IC’s Oxford-2 satellite modem ASIC will be showcased during the upcoming Electronica 2022 event in Munich from November 15-18th.
The MCM7500 is a wideband multi-carrier satellite modulator fully compliant with DVB-S2 and DVB-S2X standards, including Annex-M. The MCM7500 is used in Dialog Baseband Hub Modules as part of the XIF Hub.
The demonstration will be conducted as part of the European Space Agency’s (ESA) Free Hopper project, which aims to validate the technical maturity of advanced DVB-S2X beam-hopping using the DVB-S2X standard. Beam-hopping is a patented technique that allows highly flexible allocation of satellite capacity to areas that need it most.
ESA, under the Artes 4.0 Telecom program, has engaged Airbus France, Honeywell UK, ST Engineering iDirect and EASii-IC France to participate in the HTS Free Hopper program. The two-year project is currently in its initial phase, where equipment interoperability is tested and guaranteed before proceeding with full testing of beam-hopping scenarios.
The demonstration at Electronica, a leading trade show for the electronics industry, exhibits a high symbol rate carrier using the new DVB-S2X Super-Frame format 6 in continuous very low signal-to-noise ratio (VLSNR) mode. Further features can be demonstrated live at stand C2.148 on request. VLSNR is a form of modulation that allows satellite links to be maintained in very challenging link conditions where the useful signal’s power level is well below the noise power level.
With a culture of innovation and a long history of pushing technology boundaries, both ST Engineering iDirect and EASii-IC were instrumental in creating the DVB-S2X standard. The MCM7500 and Oxford-2 implement the latest DVB-S2X standard EN302307-part 2 which was first adopted in 2021.
