| contents | An optoelectronic oscillator (OEO) producing a signal at 45.86 GHz is demonstrated that may potentially be utilized in the local oscillator (LO) generation of Earth observation applications such as the microwave sounding (MWS), microwave imaging (MWI) and ice cloud imaging (ICI) missions of METOP 2 of ESA. Preliminary results show that the performance of this lower SWaP OEO system is comparable or in some respects better than the electrical system already used in the MWS, MWS and MWI missions of ESA. Specifically, a sidemode suppression of about 46 dB, a phase noise of -102 dBc/Hz at 100 kHz offset, and frequency stability of 30 kHz in a ten-minute interval is achieved for the 45.86 GHz signal. The OEO is a promising candidate to replace or supplement the electronic systems of phase locked dielectric resonator oscillator and frequency multipliers used currently in Earth observation. |
