24GHz single-chip radar targets broad range of applications
10/4/2012 11:37 PM EDT
With its new single-chip radar
solutions, Infineon addresses applications in industrial and commercial
sensing. The devices however also can be used collision avoidance in
industrial vehicles.Based on a SiGe process technology and operating in the
24GHz ISM band (24.0 – 24.25GHz), Infineon's new 24GHz radar sensors
feature the highest integration radar system-on-chip transceivers in the
market and a companion receive only chip, which collectively provide
system designers with the flexibility to achieve cost and performance
targets in a diverse range of applications.
The three devices in the new family are the BGT24MTR11 (single
transmit and single receive channel), BGT24MTR12 (single transmit and two receive
channels) and BGTMR2 (twin receiver). Moving from one single receiver
to two or more receive channels allows implementation of systems that
detect objects more precisely and at wider angles.
The range of
potential motion sensing applications for the new device family includes
level monitoring in storage tanks (solids and liquids), lighting
control, security systems, intelligent door openers and collision
avoidance on industrial vehicles.
The single-chip solution in an
industry standard QFN style package reduces the required board area by
up to 30 per cent compared to discrete solutions in the market. The
BGTMTRxx family simplifies designs and improves time to market by
superseding external component matching and space consuming RF
transmission lines. The resulting compact design, system flexibility and
cost effectiveness of the solution make the BGT24MTRxx family useful
for improving performance in existing applications and replacing
For energy efficient lighting, 24GHz Radar
Systems are well-suited for adjusting the intensity level of street,
industrial and office lighting by detecting moving objects or people in
the designated area.
The 3.3V BGT24MTR11 has a detection range up to
160m at 500mW power consumption and is accurate within millimetre range
for near-field sensing applications. With standard VQFN package, no
specialized equipment or processes are needed for production assembly
and test of radar systems based on the BGT24MTRxx family.
