IWR1443BOOST: Information about RX-RX and RX-TX Coupling

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: AWR1642, IWR1443, AWR1243

Hi all.

I am trying to find the value of the coupling between the different RX antennas and between the TX and the RX antennas on the datasheet of the IWR1443BOOST, but I am unable to find it.

Someone knows if this information is available on some document or someone has tried to evaluate these values experimentally?

Thanks a lot.

Hi Luca,

I'm not so sure of this either but we will have an IWR team member look into this for you.

Cheers,
Akash

Hi Luca,

This post gives gives the worst case RX-RX and RX-TX isolation figures of the AWR1642 EVM, which has the same antenna design as that of the IWR1443 EVM.

Thanks,
François.

Hi Francois
have you rated Rx to RX and TX to RX inside the chip (AWR1243 or IWR1443)?

Thanks
CDC

Hello again CDC,

We only have the ratings for the EVM itself at this time as shown in the thread cited by Francois above. If there is any update on this then we will let you know.

Cheers,
Akash
