RF & Microwave Design Engineering

Microwave Design with CST, Ansoft HFSS and Ansoft Designer
-Broadband Double Ridge Waveguide Magic Tee and load in WRD200, WRD350, WRD750
-Cavity combline filters and multiplexers around 2GHz
-Passive intermodulation testing

RF Design with CST and Microwave Office
-Several filters design and development:
Stripline technology (with air or multilayer substrate) from 2 to 18GHz
Microstrip technology from 8 to 12GHz
Cavity filter (combline) from 800MHz to 18GHz
-Multiplexers design and development on the bench
Stripline technology from 2 to 18GHz
Cavity filter (machined combline) technology from 800MHz to 2.5GHz

-Ideal design with ideal switch to see the limits:
Frequency, power, bandwidth, efficiency
-Build a transistor model with specification
-Schematic class E amplifier with the transistor(s)
-Realistic design 2 stages amplifier (Layout)

Applications to Active Phased Array Radar in X Band:
-Characterisation of a LNA: S-parameters, Gain, P1dB, Noise figure
-To find influence of unknown signal (L, S and C band) on X band on the LNA
-To design and simulate of pass band filter on ADS and Momentum to compare two low cost substrates

Application to UWB Propagation in indoor:
-Acquisition of measurements in indoor environment:
Treatment and modelisation:
-To develop a mathematic model and a computer science model (interface) on Matlab environment and correlation of multipath with reference

-To test and repair electronic cards at the process with tester devices
-Practical knowledge on all the production process of an electric card
