PROJECT TITLE: Millimetre and sub-millimetre wave GaAs Schottky diodes, detectors and mixers — M3GAAS

Coordinator: National Institute for Research and Development in Microtechnologies, IMT Bucharest 

Partners: S.C ROM-QUARTZ S.A

Period: December 2013 - September 2016

Project director: Dr Alexandru Muller 

Project team: The project team is composed of PhD, researchers, PhD students, all having a serious background in RF MEMS technologies, microsystems, microwave, microelectronics, physics, material science, etc.

CO- IMT Bucharest has a strong research team in order to accomplish all the project requirements: 13 senior researchers (CS I, CS II, CS III), 4 young researchers, 3 engineer for technology and 8 technicians (technology and electronics); in this tean there are 11 PhD and 2 PhD students. 

P1-ROM-QUARTZ will be involved and will provide expertise for technical assistance in the development and characterization of high-frequency electronic components (GHz), the professional filters used in special telecommunications. P1 team is composed of senior researchers.


The project intends to develop:

Contributions to the STAR programme objectives:

State of the art technologies regarding Schottky diodes for millimeter/submillimetre wave and THz applications have been developed in the USA, both at research as well at commercial level. The purchase of such Schottky diodes chips from the USA providers is not an easy task, because of their multiple applications

The development of millimeter/submillimetre wave Schottky diode technology, as well as the technology of monolithic integrated direct receivers and mixers based on Schottky diodes, is an essential objective of ESA, especially to guarantee European independence in terms of future Earth observation, radiometers and other scientific instruments functioning at millimetre and submilllimetre wave frequencies. 

This is the reason why ESA has strongly encouraged the development of high performance Schottky diodes, working in the millimeter /submillimetre wave frequency range, as well as monolithic integrated detectors, mixers and multiplier devices based on Schottky diodes, in European facilities.
