Currently efforts are taken to reach frequencies close to 1 THz. Aggressive reduction of the gate length has been essential in this progress, but is becoming less effective with gate lengths approaching 30 nm scale. New technological approaches are needed to reach thz frequencies. New material systems are being investigated, especially those based on antimonides. Germany TDE T106-603EF Fraunhofer Gesellschaft 2020 - 2024 Low Noise Amplifier (LNA) at 600 Gigahertz (GHz) Fractionated sub-surface sounder configurations for Giant Planets satellites exploration An investigation shall be done of the feasibility of a fractionated (multi-static) surface/sub-surface sounder configuration that fulfils the needs of the key application of interest i.e. remote sensing of the planets or moons of planets. This type of configuration allows to increase the SNR (having more than one receiver) and together with the use of advanced radar processing strategies enables the clutter removal or feature extraction. Germany TDE T206-023NA DLR - German Aerospace Center 2023 - 2024 Fractionated sub-surface sounder configurations for Giant Planets satellites exploration Very high data rate receiver for the Earth-Space link in the 22 GHz frequency for future moon exploration missions Future Moon exploration missions require very high data rates, in particular for the uplink, that are not supported by the current state-of-art on-board technology.This activity focuses on the design of a receiver capable of handling very high data rates and low SNR (Signal-to-Noise Ratio) values, making novel use of the 22GHz for TTC (Telemetry, Tracking Command) uplink.The activity encompasses the following tasks:1 - Consolidation of the high level requirements of a lunar communications architecture for the Earth-Space link 2 - Design the overall on-board receiver architecture based on th Germany TDE T306-501ET TESAT-SPACECOM GMBH & CO.KG 2019 - 2024 Very high data rate receiver for the Earth-Space link in the 22 GHz frequency for future moon exploration missions Filter by Programme TDE (3) Filter by Start Year 2019 (1) 2020 (1) 2023 (1) Filter by End Year 2024 (3) Filter by Keywords 1-Microwave Payloads (1) 2-Ground segment and operations (1) 9-Technologies applicable to several Cosmic Vision Missions (1) Filter by Contractor DLR - German Aerospace Center (1) Fraunhofer Gesellschaft (1) TESAT-SPACECOM GMBH & CO.KG (1) Filter by Country (-) Germany (3) Filter by Application Domain EO-Earth Observation (1) EXP-Exploration (1) SCI-Space Science (1) Filter by Technology Domain (-) 6-RF Subsystems, Payloads and Technologies (3) Filter by Competence Domain 5-Radiofrequency & Optical Systems and Products (2) 3-Avionic Systems (1) Filter by Activity Status Closed (3)
