A wide range of equipments is at lab's researchers' disposal to cover all their needs for passive or active devices characterizations, for experimental validation of theoretical models and for new architectures design in telecommunication systems.
These equipments are organized under three themes

Radiofrequencies and Microwaves characterizations

 

Four Vector Network Analyzers cover a wide frequency domain from radio to millimetric waves. These equipments allow small signal frequency characterization for passive and active devices which can be planar, coaxial or packaged. A very wide band measurement system allows 40MHz to 110GHz full characterization with only one sweep in coaxial mode.


Other characterization tools are also available. For example, noise measurement up to 26GHz is proposed for noise figure or noise parameters extraction. Furthermore, we have solutions for spectral characterization up to 75GHz and for sub nanosecond time domain measurement.

Microwave-Photonics devices

Several equipments are available for microwave-photonics devices characterizations like E/O and O/E converters used by researchers. For example, a calibrated optical test set with an integrated laser source at 1300nm and a high-speed photodetector can be used up to 20GHz. A 65GHz gold calibrated O/E converter is also at researchers' disposal for very high speed applications.


Other equipments for digital signals generation and analysis allow data transmission evaluation of performances in microwave-photonics architecture systems.

Two kinds of generators are proposed. A pseudo-random bit generator is used for high bit rate PRBS signal up to 3Gbits/s. A vector signal generator can be used when complex modulations are needed.

Two kinds of receivers are available for signal treatment and analysis parts of digital links. A complete system consists of a frequency translator receiver and an analogue to digital converter, all included on VXI format and associated with software. It provides full characterization of the link. Furthermore, a high bandwidth digital scope (up to 6GHz) can be used for real time domain analysis of transmitted signals.

EMC Characterization

A large volume (130m3) is available for electromagnetic characterizations which needs a noiseless area without any external disturbances. A certified 25m2 Faraday cage is already integrated in the new MINATEC building and can be used by researchers. A future development is planed to create an anechoic chamber, inside the existing Faraday cage. Thus, it will be possible to have a complete tool at disposal for antennas and wireless links characterizations, also for radiation phenomenon study on researcher's devices.
