The Alphasat I-XL, launched in 2013, included beyond its main task several ESA TDPs (Technology Demonstration Payloads). TDP5 includes a Q-/V- Band communications experiment to assess the feasibility of these bands for future commercial applications.
Key technical challenges:
- Functionality at Q-/V-band frequencies (Rx: 37.85 to 39.50 GHz, Tx: 47.85 to 48.15 GHz)
- Accurate design and manufacturing
- Mechanical tolerances according to specification
- Adequate RF measurements and testing
Key functionalities:
- Rx and Tx at Q-/V-band frequencies
- Automatic alignment of linear polarized signals
