AWR1642BOOST: unit in mmwave studio time domain plot and detailed specifications of antenna gain

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642

Hi, I have two questions here.

One is about unit of time domain plot in mmwave studio, and another is about detailed specifications of AWR1642BOOST which I can not find in the user guide.

In time domain plot, the y-axis unit may be dB or dBi, right?

What does "codes" mean?

I'd like to construct a similar simulation environment as AWR1642BOOST in MATLAB.

In order to make power of received signal reasonable, I've to know rx gain, noise figure of AWR1642 in receiver pre-amplifier.

Then calculate peak power according to radar equation. Do you think it make sense?

How can I find these specifications?

Thanks a lot!

Hello ,

1) In the time domain plot the Y -axis is the ADC code word value.

2) The Rx gain is set based on what you program in the profile config. The noise figure value can be found in the datasheet.

Hi Vivek Dham,

1) Well...it seems like convert ADC code word to dB is just a linear transformation.

Is there any function or code to do this?

Hello,

You can refer to some of the other threads in this forum regarding conversion of ADC code to dBm value. One of such threads is :
