Callisto is pleased to announce that the project GRACY in collaboration with IEMS ( University of Lille) and IMS ( University of Bordeaux ) has been selected by the Agence Nationale de Recherche in a frame program for Nanotechnologies and Nanosytems.
"The GRACY proposal is a fundamental research project and focuses on graphene‐based circuits dedicated to innovative applications for communication systems. This ambitious project addresses two academic partners (IEMN and IMS) and one industrial partner
(Callisto). The proposal involves innovative solutions for the information and communication technology, by aiming to demonstrate the capabilities of graphene microwave devices to exhibit performances beyond those of currently available high frequency transistors.
The GRACY project proposes to study graphene‐based electronic circuits operating at microwave frequencies, and their integrability into communication systems. The proposed research includes graphene material synthesis, devices and circuit technology, and a
demonstrator for a specific application. In particular, it focuses on increased performance in radiofrequency (RF) electronic components for low noise amplification, avoiding the need for cryogenic cooling.
The GRACY project is targeting 5 challenging objectives:
- Produce a Chemical Vapour Deposition (CVD) graphene with large domain transport properties close to those of single crystal flakes
- Optimize processes and transistor structures for obtaining key performance figure of merit suitable for microwave applications
- Optimize compact model for passive and active graphene based devices for microwave circuits design
- Design and fabricate the first graphene low noise amplifier (LNA) working at microwave frequency
- Fabricate and test a demonstrator for industrial application."
