At the moment we are developing an innovative RF predistortion chip making use of a financial instrument named “Business Lab” provided by FILAS s.p.a.


About Filas

Filas, the Financial Investment Agency of the Regione Lazio, promotes relations between research and industry in Lazio and stimulates entrepreneurship through the development of innovative models - as well as models that have proved successful in the most advanced European countries - in order to promote start-ups and new entrepreneurial activities through venture capital and other forms of financing.
Filas sustains and strengthens new initiatives capable of creating added value and new employment through financial support and managerial know-how.

About Business Lab

The Business Lab, a Centro Atena Business Unit, promotes technology transfer, spin-offs and catalyses the work of universities, research centres, businesses and venture capitalists in Lazio.
The Business Lab represents an innovative model for technology transfer to create start-ups.

The Business Lab project is conducted in collaboration with the Department of Electronic Engineering of the University of Rome "Tor Vergata".

Linearizer Idea

The Linearizer is, inside the transmission systems, an elaboration block which permits to enhance the linearity and then the transmitted signal fidelity without decreasing the system efficiency. System efficiency, measuring how the DC power is employed,  is of primary concern in mobile apparatuses because of it directly influences the battery life.

Up to now this type of circuit is generally designed for the specific power amplifier to linearize and in HMIC (HybridMicrowaveIntegratedCircuit) technology exploiting the hardware tunability of this kind of technology production.

The HMIC technology is inherently poorly repeatable and not suited to mass production, expensive and time consuming if tuning is required, significantly weighting and bulky.

Thanks to the MMIC technology and our innovative approach all these limitations will be overcome.
