This domain of the platform focuses on architecture as well as on the development of new digital communication links using electro-optical modulation solutions over optically generated millimeter wave carriers.
Radio over fiber digital communication system
Several technical solutions are proposed to generate complex analog or digital waveform, on IF, RF or millimeter wave carrier :
Vector signal generators, bandwidth up to 1GHz on I and Q channels
Arbitrary signal generator up to 12Gsample/s, 10 bits, 32Mpts, on 2 channels
Pattern generator, bit rate up to 3.3Gbit/s
Up and down conversion using external mixer and millimeter wave LO
Several hardware and software solutions are also proposed for analog to digital conversion, demodulation processing and signal analysis :
Vector signal analyzers (VSA) based on different hardwares (BW up to 80MHz)
Oscilloscopes 6GHz in one shot and 20 GHz in repetitive mode for higher BW
Keysight Advanced Design System (ADS) and Vector Signal Analyzer (VSA) softwares
Generation to analysis flow in a wideband communication system
Many optoelectronic components are also available and can be implemented to build RF on fiber links used in high speed communication :
Laser diodes
Optical Modulator up to 40Gbit/s
Optical MUX / DEMUX
EDFA
High speed photodiodes 70GHz and 100GHz
65GHz calibrated photodetector used as reference standard for frequency characterization of E/O and O/E converters
