AWR1843AOP: AWR1843AOP use without boost or EVM boards

Lilia ROUIZI

Part Number: AWR1843AOP

Hello everyone,

I'm currently on an internship where I have to work with radar sensors in an automotive application.

To make it short, the choice was quickly made on the AWR1843AOP but for pricing matters I will only be able to get the chip (no boost neither EVM boards). The sensor will be used with an Rcar H3 processing card using a CAN bus to transfer data to it.

My question is about the feasibility of this process, can the chip be directly used with a microcontroller (adding some links, resistors and capacitors) ? Are there some tutorials/guides on how to use the AWR1843AOP directly. Any information would be gladly received since I have little time left on my project.

Many thanks !

Lilia.

    Hello,

    Unfortunately, this will not be possible. Using the sensor requires a careful PCB design to make sure that the power supply design and ripple requirements are met. Additionally, there are several signals needed to run the sensor (reset signals, sense on power signals, SPI/UART signals, etc). The device also requires very specific decoupling capacitor selection and placement very near to the power pins with low impedance return path to device GND, so this can only be done in a PCB design and not by placing these components on an external board. 

    I would strongly recommend against trying this. Even if you do manage to get the device up and running, you will have very poor performance relative to a proper PCB design with the sensor.

    Regards,

    Hello Adrian,

    Thanks for the quick answer. Could you please recommand an alternative that would do the work and closer in price.
