Design of a single and dual satellite low noise block downconverter in the Ku band frequency range

Geneva Area, Switzerland

Develop a L band satellite tuner

In a small design team we have developed an DVB RF Tuner in 90 nmtechnology. I have participated at each conception step: - take in place verification CAD Flow in particular LVS, DRC and extraction. - Design and Layout of diiferrent blocks ( Low pass Filter calibration, Baseband Amplifier, high speed divider, DAC, Antenna tunning Control, VCO....) - Top Level simulation with Fast spice simulator - Check Filling and Cheesing after foundry post processing. - Measurement and Characterisation

Optimization of wireless CDMA transceiver with a new passive integration method based on thin film technology called PICS (passive integration connective substrate):- Co-simulation of passive and active dies ( two technologies: BiCMOS and PICS).- Study of CDMA receiver to see passive components which could be integrated.- Measurement of RF performances (NF, IIP3, gain…) on silicon and comparison with simulation. - Modification of active die (LNA, mixers) to have better performances. Learned skills: System knowledge (ZIF receiver), RF design (LNA, mixer), Instrumentation (noise and S parameters measurements), Electromagnetic simulation.

In the UMTS division with project manager of the new platform (Video telephony, video mail box, streaming) I was in charge of the test of the third generation services on the new mobile phones. Learned skills: UMTS network, 3G mobile phones.
