TDK Corporation launches UWB integrated test system for UWB device
evaluation and measurement
May 27, 2005
– TDK corporation announces
the availability of a total solution integrated UWB evaluation and
measurement system. Sales of this new system will start in both Japan
and the United States in June 2005.
The total solution test system consists
of wideband antennas, anechoic chambers, and software that speed up the
process of compliance measurements. This automated test system performs
the high precision measurements required as described by the FCC Rule
Part 15 Subpart F UWB devices. A two-axis rotating structure and
polarized automatic switching antennas are employed to measured
emissions with the radiation patterns being displayed in three
dimensions. The automated system, which is controlled via software
developed at TDK, significantly reduces test time and increases the
utilization of the test facility.
A key component of this new test system
is TDK's original pyramid-shaped absorber material which was
specifically designed for high absorption of oblique incident angle
radio waves. This material reduces reflection of oblique incident angle
radio waves to the side walls, ceiling and floor and allows anechoic
chambers to be made substantially smaller.
TDK Test Services (TTS), a division of
TDK R&D Corporation (TDK's research and development subsidiary in the
United States) has been providing high-precision UWB measurement and
evaluation services since October 2004.
About UWB
UWB is the next-generation
communications technology that is expected to achieve data rates in
excess of 100 Mbps over short distances by using radio waves over an
extremely broad bandwidth. Because of its ability to transmit multiple
streams of high-definition video, it is expected that UWB will be
employed in a wide variety of electronics devices including digital
audio-visual equipment, and PCs using wireless USB and wireless 1394.
The FCC authorized low-level RF communications over the 3.1 GHz to 10.6
GHz bandwidth in February 2002, and the International Telecommunications
Union, Japan, and European countries are now developing regulations for
the use of UWB transmitters outside of the US. |
