they command, we can explore opportunities for
our improved T-Contact-based Datamate connector
portfolio in areas like unmanned vehicles, avionics and
satellites.”
“The T-Contact presents a unique proposition to
engineers. Because of our proprietary one-piece
design, the constituent materials can be significantly
thicker, thus reducing the overall contact resistance and
increasing conductivity, as well as allowing enhanced
thermal properties to be benefitted from,” adds
Ridhwan Islam, Field Applications Engineer, Harwin.

, AN AVX GROUP
COMPANY, ANNOUNCES NEW PORTABLE
MILLIMETER WAVE MEASUREMENT SYSTEM
AVX Corporation, a leading manufacturer and supplier
of advanced electronic components and interconnect,
sensor, control, and antenna solutions, announced that
Ethertronics, an AVX Group Company, has released
the new Ethertronics
®
ETH-MMW-1000 Millimeter
Measurement System: a compact, cost-effective,
extremely accurate, and easily adaptable portable
solution for testing 5G antennas and other devices at
millimeter wave (mmWave) frequencies. Suitable for
all mmWave system development and validation —
including 5G communications, telecom industry research
and development, university research, and other
mobile communications and mmWave device testing
— this new modular, mobile, far-field measurement
solution offers a shielded environment to ensure stable
measurement results over a wide frequency range,
requires no up or down frequency conversion to ensure
excellent phase stability and accuracy, and is easy
to install and relocate within both new and existing
laboratory and production environments.
The ETH-MMW-1000 Millimeter Measurement System
is a fully anechoic aluminum enclosure on a mobile
chassis with steerable lifting wheels that enable quick
and easy relocation and provide optimal stability
during measurements. It is equipped with sliding
doors for easy access to the center of the system and
the device under test (DUT), as well as a distributed
axis positioning system that is comprised of a height-
adjustable, PVC, azimuth mast rotator that rotates the
DUT about the Phi axis and a Theta ring positioner that
elevates the measurement horns around the DUT.
Designed to accommodate various device sizes,
weights, and form factors, the system is available with
several mechanical interfaces for the mast, including
a 300mm-diameter half-sphere with dedicated notches
that allow users to easily position DUTs, such as
tablets and phones, both horizontally and vertically.
Standard system components also include a slip ring
within the mast that allows users to bring both power
and digital control signal to the DUT, a rectangular
horn antenna, rubberized absorbers, an integrated
gigahertz control unit, and an assembled RF path
comprised of high-performance cables, rectangular
waveguides that minimize path losses and ensure
maximum measurement accuracy, measurement
horns, amplification stages, and switches. No up or
down frequency converter is used on the RF path
to ensure excellent phase accuracy and stability.
The Millimeter Measurement System also includes
an integrated computer complete with Ethertronics
Antenna Measurement software for measurement
control and data acquisition and Ethertronics Antenna
Viewer software for post-processing and tabular or
graphical data output. In addition, each system comes
with installation, training, and warranty services.
Optional components and services include calibration
kits, custom mast and interface materials and designs,
and post-warranty service plans.
The Millimeter Measurement System can perform
passive antenna testing, active signaling, and non-
signaling testingwith complete devices and is compatible
with most vector network analyzers (VNAs), spectrum
analyzers, and communication testers manufactured by
Keysight Technologies, Rohde & Schwarz, and Anritsu.
“Designed with both current and future application
utility in mind, the new ETH-MMW-1000 Millimeter
Measurement System leverages Ethertronics’ antenna
design, manufacturing, and testing expertise, an
array of quality components, and a space-efficient but
comprehensive and effective modular, mobile design
