Advanced Microwave Optical Links for LO Distribution in Satellite Payloads
01 January 2006
Microwave optical links can replace electrical cables and harnesses for master oscillator distribution. This paper presents optical links designed and optimized for transmission of Ku-band LO signals with high performance: the transmitter is based on the DSB-CS modulation technique, and the receiver consists in an injection locked photo-oscillator. Such a sub-system is well suited for the optical distribution of high spectral purity microwave signals to numerous receivers, as required in satellite payloads
