Researcher & RF Engineer 2010 - 2012

Researcher at Communication Department on Cantabria University. I have

been working in passive circuits design mainly. I was involved in two

projects for Indra Systems S.A., one of the largest corporations in

Europe with a focus on information technology, security and defense

systems. As part of an international team, I was engaged in one NATO

project, and responsible for the design and optimization of a mono-pulse

tracking system for unmanned aircrafts.

. Orchestrated the development of an antenna feed system for Hispasat

Satellites in the Amazonas-3 project. Some components of the antenna

feed design are: filters, duplexers, orthomode transducers, polarizer,

transitions and antennas.

. Trusted with the makings of the drawings for the mechanical

construction, measurements of prototypes and all the technical

documentation for both projects.
