The objective of the mini-project (this activity goes hand in hand with the ''Characterization of W-band propagation channel through ground-based observations'' activity) is to develop the technological building block needed to start characterising the W-band propagation channel. The use of higher frequencies is becoming necessary for supporting feeder links of High Throughput Telecom Satellites due to the larger bandwidths available. Q and V bands are now being considered as a baseline for next generation systems. The next step will be to look at W band. In order to understand the system sizing, it is necessary to have a good modelling of the propagation channel. So far no measurement campaign has been done, therefore it is needed to start characterizing the W-band satellite propagation channel. This project will consist of 3 parallel activities: 1) Design of a W-band beacon payload; this core activity shall start from the identification of launch opportunities (GEO or non-GEO), and then designing a W-band payload for characterising the W-band Satellite propagation channel. This activity shall define the specifications of the main W-band component for the beacon transmitter. Timeframe: T0 - T0+12m 2) Design of the propagation terminal and identification of technological developments. Timeframe: T0+6m - T0+18m 3) Technological development of the key components for the beacon transmitter and propagation terminal receiver (i.e. Wband SSPA, W band LNA with high gain stability, low phase noise W band Frequency Generation unit). Timeframe: T0+12m - T0+30m
