Hi,

I want to know detailed antenna deployment, i.e., the inter-spacing between TX/RX elements and the distance between TX and RX, as shown in the following figure

Thanks

Hello Yao,

The figure is not visible in the post. But I assume you are asking about the antenna spacing on the AWR1642BOOST EVM. The complete layout database and gerbers files are available on the wepage, https://www.ti.com/tool/AWR1642BOOST.

From the gerber files of layout files you can measure the exact distance and spacing.

Regards,

Vivek

Hi Vivek,

Yes, I want to know the antenna spacing on the AWR1642BOOST EVM. But the documents of user guide and datasheet on your referred webpage did not mention it.

Thanks

Hi Vivek,

Also I want to know whether AWR1642 has ability to do TDM-MIMO or two TXs have to transmit signal at the same time.

Thanks

Hello Yao,

Yes, 1642 can do TDM MIMO, and also two Tx can be enabled simultaneously in a chirp. We have a very flexible chirp configuration options programmable by the user. You can find the details in the mmwave SDK documentation. In the chirp configuration you can select each chirp which Tx You want to use (Tx1, Tx2, Tx1+Tx2).

regards,

Vivek
