IWR6843AOPEVM: mmWave Sensor function

Marcus Gear

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: IWR6843AOP,

Hi, would the IWR6843AoP or DesignCore™ Industrial mmWave Sensor Starter Kit be able to detect an external 60 GHz signal using the integrated antenna?

Is the module capable of converting (rectifying) the detected frequency to a DC voltage?

Thanks,

Marcus

    Hello Marcus,

    IWR6843AOPEVM is functionally meant to be used a Transmit+Receive device such it captures reflected waves from it own transmission.

    If you could help us understand the application you are tying to implement then we might be able to guide you better.

    Thank you,

    Vaibhav

    Hi Vaibhav, 

    The application is a 60 GHz detector, its purpose is to detect if a 60 GHz signal (or 57GHz to 65GHz) is present at any location. This must be omnidirectional. 

    Hoping to then rectify the detected frequency wave into a DC signal, amplify and produce enough voltage to light an led indicator. 

    Simple in theory, but proving difficult to find components. I've not yet sourced diodes capable of operating at 60 GHz+.

    Thank you for your help, 

    Marcus

    Marcus,

         Yes, it's simple in theory, but it may be convoluted to implement. Tentatively, device does not have provision to "rectify the detected frequency wave into a DC signal, amplify and produce enough voltage to light an led indicator"

    Having said that, you may want to explore below solution: 

    Any 57-65GHz signal is a interfere to the mmWave sensor, Device is supported in the 60-64GHz band only.

    Any external signal in this band would be treated as interference to operate the radar faithfully. And we have mechanism to detect the interference and avoid it you could refer to below app-note and Training video.

    You may want to explore idea from here to develop your solution.
