Circuit and microwave systems designer through the use of circuital and electromagnetic simulators. I have a strong expertise with microwave laboratory instrumentation and a good theoretical background in the active and passive components including the design of antennas and power amplifiers. I have also a good competence in microwave filters design. I have many years of experience in research and development in the field of point-to- point telecommunications systems, focusing in particular on the architecture definition and layout design of transceiver board. I have a good knowledge of regulatory documentation and a considerable competence on the experimental verification of the many features of the board. I draw up the hardware description and qualification test papers. I’m also able to manage design activity, relations with customers and suppliers and I have responsibility on final unit. I attend regularly at conferences and workshops on the latest topics of microwaves in telecommunication area and also aero-naval and biomedical fields of application. Aptitude to communicate with people of other departments, I’m also disposed to trip for working reason. WORK EXPERIENCE

07/13 – 06/14. Exprivia Telco & Media SpA, Trezzano S/N (MI) Microwave Designer. Consultant at ALCATEL-LUCENT.

Hardware designer in the Microwave Laboratory Group. Activity focused on point-to-point telecommunication equipments development. Company is one of the most important worldwide suppliers. Design of the transceiver unit e verification of the system requirements. Preliminary phase addressed to architecture definition, through circuit and system simulations, and selection of proper devices. Microwave laboratory activities of board testing and tuning. Managing of the supplier relationship and measurements on test samples, in particular ceramic filters and isolators. Full packet microwave radios link testing at 6 and 11 GHz for international standard requirements verification.

Project developed:

RF / IF unit, used in the “Aurelianus” apparatus for transmitting packet data in the frequency 4 GHz. Cooperation within group in Tx, Rx chain architecture design. Measurements on selected part number. System simulation aimed to the architecture definition and schematic entry. Cooperation with support engineering department for layout definition. Electromagnetic simulation of passive devices and power amplifiers matching networks design.

06/05 - 09/2012 NOKIA SIEMENS NETWORKS – Cassina De’ Pecchi (MI). The company is the result of a joint venture between Nokia and Siemens TLC, took place in 2007. Microwave Engineer. Designer of the hardware cards, inside R & D Microwave, used in Radio Links Telecommunications equipments by major infrastructure such as telephone companies, of which the company is one of the leading suppliers in the world. Corresponding role as the previous one, focused on the design of the in radio frequency circuitry of the unit. The initial phase supported by electromagnetic CAD and other software tools, regarding the definition of the architecture of the card, sizing of the components and layout definition. The next one, carried out through laboratory activities, of key performance verification and compliance with the design specifications of the apparatus complete, of which the card is the active part. This phase is particularly devoted to the identification of defects in design not recognized in the preliminary stage. I also supported testing activities of the radio link such as BER threshold measurements. Responsibility on the final, that is, on the apparatus complete, including mechanical parts needed to assemble the base station. Main projects

RF / IF unit, used in the “Phoenix” apparatus for transmitting packet data in ranges 3.5, 11 and 13 GHz. Implementation of new solutions for the achievement of the design specifications.

RF / IF unit, used in the “E-Band” apparatus for transmitting packet data in ranges 60/70 GHz. Contribution in feasibility study of the board architecture.

RF / IF unit used in SDH(Synchronous Digital Hierarchy) transmission system in the frequency 28 GHz. The high frequency has been a challenge for the search of suitable components in contrast to the design requirements to contain the cost of construction of the apparatus. It is in fact required a technology cheaper than the mainstream, but not yet fully reliable.

RF / IF unit used in synchronous transmission SDH in the frequencies 11 and 13 GHz. Calibration of the power amplifier and design of microwave filters used in the board.

RF / IF unit,used for the 802.16 standard, known as WiMAX, in the ranges 2,4 and 3,5 GHz. I have developed some parts of the WiMax card which in 2005 was a new design even within the department. Result: Complete apparatus obtained for both frequencies of operation with a particular characteristic from me managed regarding the possible time division operation, alternative to the usual frequency division. I have also attended to several conferences, such as the European Microwave Week (editions 2009, 2010.2012), which allowed me to deal with topics of interest such as design filters and other passive microwave components, developments on MMIC technology, advanced simulation techniques, even addressed to other issues.

01/05 - 03/2005 GSE Srl. - Prato Company of electrical supplies, sales and service of UPS Technical and Sales. My role spaced from contact with customers to repairs and shipping management. KEY SKILLS

Technical tools: I have developed a good knowledge of the following software simulation and calculation: Wasp-Net, Mician, CoupleFil, ADS Agilent Technology, Microwave Office and VSS of AWR, COMSOL MP, HFSS of Ansys and Microwave Studio of CST.

Electromagnetic simulators (CST and HFSS) represent to me the most valuable and daily working tools, because they allow the electromagnetic analysis of a wide range of geometries: from passive devices easier to complete layout of the card, both in frequency and in time domain. In addition they are also able to perform thermal and mechanical analysis, signal and power integrity and low frequency simulations. I’m able to manage laboratory instrumentation with LabView and also I’ve a good knowledge of modeling and programming with Matlab and and I’m also a basic user of Simulink.

Technical and laboratory field: performance testing of the designed radio cards, required for the necessary certification of equipment, has allowed me to develop a good manual dexterity with tools such as network analyzers, spectrum analyzer, oscilloscopes and meters of NF.
