Generating local oscillator (LO) at frequencies beyond 100 GHz is a challenge in many Earth Observation missions. This usually realised with a relatively low frequency LO generation followed by a number of multipliers, ending up in a rather narrow-band operation and pretty inefficient RF power conversion. Furthermore, the LO has to be implemented very close to the receiver since cable losses are high at those frequencies, not to mention multi-pixel instrument that require the distribution of the LO to multiple heterodyne receivers. Microwave Photonics offers the possibility of a direct high frequency generation, with easy distribution via fibre, as demonstrated in the activity 102-05ET – Microwave Photonics Millimetre-wave Generation – of the TRP 2007-2010 workplan. However, the main limiting factor of the experiment was the low output RF power of the photodetector which is proposed to be addressed in this activity. In a first phase, the state of the art of high power, high-speed photodetectors shall be reviewed. From this, some preliminary structures aiming at frequency generation of 100 GHz and beyond, shall be proposed and analysed via simulations. In a second phase, the detailed design of the most promising structure shall take place and a set of devices shall be realised. This devices shall betested into a breadboard of a LO operating at frequencies beyond 100 GHz. Procurement Policy: C(1) = Activity restricted to non-prime contractors (incl. SMEs).
