Biography

Val Dyadyuk has extensive experience in the RF system engineering and mm-wave design gained over the past 30 years. He has held various senior positions in prestigious public and private organizations.

Val started his career as a Research Engineer at University of Radio Electronics in Ukraine (1970 – 1975) and worked on EM simulation of microwave devices with anisotropic medium.

From 1975 to 1992, he worked at the Institute for Radio Physics and Electronics, National Academy of Sciences of Ukraine as a Leading Design Engineer and Head of the Microwave Engineering Branch. He led a number of R&D projects and developed variety of mm-wave devices and RF modules for Radar and Communication Systems, medical and industrial mm-wave equipment including the sub-millimetre wave interferometer for experimental thermonuclear reactors TOKOMAK.

In 1992 he joined the Scientific & Research Institute of Radio Electronic & Diagnostic Systems (Ukraine) leading development of a mm-wave radio link as a Head of the High Frequency Branch.

In 1993 Val was appointed Director of Research at the SCAD Scientific & Industrial Group (Kharkov, Ukraine) where he was responsible for design and pilot production of a marine microwave radar sensor and mm-wave equipment for biological and medical applications.
Due to the nature of employment and citizenship, all publications for period 1973 – 1994 available in public domain were in Russian.

Since moving to Australia, he joined RF Devices Pty Ltd where he designed a high-linearity wideband HF amplifier. Shortly afterwards he joined British Aerospace Australia designing the Frequency Management System for the JORN Radar Networks.

Val Dyadyuk joined CSIRO in 1997 and contributed to the success of several research projects, including design of a microwave power distribution network for the CEA-Mount Advanced Technology Demonstrator, a feasibility study of a wideband vector modulator, development of the Traffic Management Radar demonstrator, design of MMIC amplifiers (as a part of development of CSIRO’s HBT technology that led to Epitactix spin-off), and design study for a Millimetre-wave Broadband Wireless Access System.

In 2001 he made a major contribution to analysis of wireless technologies and applications, propagation issues and system architectures, operating frequency selection and formulating requirements for the RF front ends, antennas and integration technology suitable for a low cost manufacturing. He has prepared a report that summarised all the above findings and has been used as a foundation and justification of the Gigabit Wireless Research program, which has been proposed jointly with Stephen Giugni and Oya Sevimli and successfully carried out in 2002-2006.

He has also participated in development of a wafer scale thin-film multi-chip-module integration designing microwave test structures for the process characterisation and interpreting the test results that led to the patented CSIRO integration process (2002 –2004).

Val led the Gigabit Wireless Research Projects in 2002-2005. He has made a major contribution to development a high data rate (1Gbps) W-band link that was the only example of such a system at this frequency reported worldwide (2003-2004). Val initiated and led a team work on building a mm-wave system and propagation study test bed at Marsfield operating since 2003.

He developed concepts of the Multi-Gigabit millimetre-wave wireless links and designed several key RF components such as wide-band RF front end modules, designed and tested wide-band mixer MMICs (UMS BES wafer run, 2004-2005), specified and developed unique IF filters that have been essential for implementation of the CSIRO’s innovative frequency-domain multi-channel wireless communication system concept.

Val has been a technical advocate and RF system architect of the world’s first Multi-Gigabit Wireless Link successfully demonstrated at Marsfield on 6-Dec-2006, and he has played a major role in its development, integration, debugging and testing.
