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.
