We have demonstrated a 16.8 GHz photodiode module that has survived 18 months on the ISS as part of the Materials International Space Station Experiment (MISSE) 7 mission without any change in device performance. This module was subjected to launch vibrations, as well as harsh space environment, namely temperature cycling from -157 °C to +121 °C 16 times a day, proton radiation from the inner Van Allen belt at the South Atlantic Anomaly, and GCR. This experiment serves as a pathway for increasing the TRL level of these photodiodes to 7 and beyond, thus, getting them space qualified for several NASA missions.
