WELCOME
TO NMDG – Leading beyond S-parameters
|
|
NMDG develops and commercializes products
and services that ” characterize
and analyze beyond S-parameters"
the behavior of active high-frequency
(HF) electrical components under realistic test
conditions. The main focus is on the non-linear
behavior of these components.
NMDG is working to provide the best solutions
for active component characterization and integration
to a wide range of customers in high –
frequency electronics and communications to
make technological advancements that drive and
optimize productivity.
Through partnerships and co-operations with
leading academic and research institutes, NMDG
is committed to empower the research engineer
with the advanced tools that provide the competitive
advantage.
A close and personalized interaction with our
customers is of paramount importance to NMDG.

History of our Company
Founded by Dr. Marc Vanden Bossche in June 2003, the roots
of NMDG go back to 1990, when he started after
his PhD. the Hewlett Packard R&D group at the department
ELEC of the "Vrije Universiteit Brussel" (VUB).
This group worked with the Santa Rosa- based Hewlett Packard
NMD division that developed and commercialised
vector network analysers. The R&D team was baptised NMDG,
where the “G” was referring to
Group. Hence NMDG stands for “Network
Measurement and Description Group”. In 1999, NMDG became
part of Agilent Technologies.
Since NMDG was founded, the group has been researching and
developing "Large-Signal Network Analyser Technology"
and had the opportunity to work with some outstanding research
institutes in this area.
In December 2002, the key contributors to LSNA technology,
Marc Vanden Bossche (view),
Frans Verbeyst (view)
and Jan Verspecht were recognized by ARFTG
for the theoretical and practical achievements related to
non-linear measurement science.
In May 2003, Agilent Technologies licensed the development
work done by NMDG to Maury Microwave. End of May 2003, Maury
Microwave sublicensed the Agilent developed IP to NMDG Engineering.
Between 2003 and 2008, Maury
Microwave and NMDG worked together on
the commercialisation of the first commercially available
large-signal network analyser, the MT4463.
Since June 2008, NMDG is working with Rohde & Schwarz
to enable the R&S VNA to characterise in time and frequency domain the harmonic behaviour of high-frequency components,
including diodes, transistors, power amplifiers etc...

History of LSNA Technology
While Agilent NMDG did play a key role in bringing measurement,
modeling an simulation for nonlinear HF components coherently
together, research work was done by others in parallel. This
work contributed and still contributes to what LSNA technology
is today and will be in the future.
If you want to learn more about the history of this technology,
the article “History
of Nonlinear Microwave Measurements”, written by
Prof. A. Barel, dept. ELEC – Vrije Universiteit Brussel
and published in Revue HF, gives a good overview and contains
an extensive reference list. This article can be downloaded
