Power damage threshold in millimetre wave radar modules?

Neil Salmon

I'm interested in using the millimetre wave radar modules and i'm concerned that power may enter the receivers from very close objects, such that the power levels might be sufficiently high to cause damage to the receivers. The TI modules might also inadvertenly receive mm-wave power from other sources in the lab. It would therefore be helpful to know what the damage power thresholds might be for the TI receivers in the radar modules. Would know that these damage threshold power levels would be?

many thanks,
Neil

Hello

You may want to play with Receiver gains and Transmit power changes to see what works for the object type.

Have you looked into those options?

Thank you for your response. I really wanted to avoid potentially damaging sensitive front-end components by adjusting gains to see what happens. It would be useful just to know the ballpark figure for power input to the front end, before damage starts to happen. That way it would be easy to avoid having to replace a whole circuit. Many thanks, Neil
