AWR1243: AWR1243P

Part Number: AWR1243
Other Parts Discussed in Thread: AWR2243, , AWR2243BOOST

Hello,

I know TI use to produce AWR1243P that can be driven by an external RF LO (LFM at 20GHz). My intent is to make multiple AWR1243 boards working together keeping the phase coherence among the received signals. Is there an evaluation board for that type of integrated radar transceiver?

Thanks

Dear Antonio -

Thanks for the post and welcome to E2E!

For the AWR1243, there is a development module: https://www.ti.com/product/AWR1243#hardware-development

For the AWR2243, there is also a development module https://www.ti.com/product/AWR2243#hardware-development

Additionally, you will also see there is a four chip cascade design in same list

along with some additional collateral: https://www.ti.com/lit/an/spracv2/spracv2.pdf , https://www.ti.com/lit/ug/swru553a/swru553a.pdf

Further, a two chip version using AWR2243 is presented here: https://www.ti.com/tool/TIDA-020047

Thanks Josh for the prompt reply. However, all this modules, included the ones with cascaded chips, do not allow to drive with the same 20GHz ramp different radar transceivers spacially separated. Our MIMO approach is based on widely separated antennas, not co-located ones. So we come back to my initial question: is there any EVM where I can externally plug my 20GHz ramp?

Thanks

Antonio

If you look at the AWR1243 or the AWR2243 module, the 20GHz SYNC_IN (N10) and SYNC_OUT (P11) pins are available on header J1 & J5 (SYNC_IN) and J5 & P2 (SYNC_OUT)

https://www.ti.com/lit/zip/sprr415 (AWR2243BOOST)

On the four chip cascade reference, the 20GHz sync signals are routed from one of the ICs to all the others and then back to first IC already.
