Product Brief
24GHz Chipset-Family
for Industrial Applications
Why Infineon’s 24GHz solution?
The BGT24Mxx family is the highest integrated 24GHz ISM Band Radar Transceiver Family
currently in the market. It saves ~30% board space compared to discrete line ups. Infineon
offers 3 different components, the BGT24MTR11 which combines one Transmit- and one
Receive channel, the BGT24MTR12 which comprises one Transmit- and 2 Receive channels,
and the BGT24MR2, a chip with 2 Receive channels, combinable with both chipsets.
There is far more to Radar Applications than what springs to mind immediately! It’s not all
about submarines and weather forecasts. In fact, they are something that we come into
contact with every day! They can be found in tank level meters, street or office lighting and
intruder alarms, just to give a few examples.
In an industrial environment, energy efficiency becomes more and more important. At the
same time, certain health and safety regulations have to be observed.
Thanks to Infineon’s new 24GHz Radar product family BGT24Mxx, these needs can now be
addressed. The BGT24MTR11 makes it possible to have products in applications with a far
higher sensitivity than were previously possible with other sensors. Doors will open only if
someone actually wants to walk through, for example. And the person does not get caught
between the sliding doors. Where it is important to detect also the position of the person
or object in the area, the BGT24MTR12 or a combination of one transceiver chip with the
BGT24MR2 is the ideal choice.
The high integration of the Infineon solution – transmit channel and receive channel on one
chip – saves expensive PCB space and makes the design easy as no 24GHz RF-Matching/
RF-Transmission Lines are required. The industrial standard VQFN package can be mounted
in standard SMD lines.
