CC1310: IQ Patch for CC1310 (CC13xx) for TX?

Muris Trax

Part Number: CC1310
Other Parts Discussed in Thread: CC1260

Hello,

I am starting a new project and CC1310 almost fits all my requirements.

I need to receive IQ samples (which is enabled using the IQ Patch), but I also need to send them back to the TX. I understand that this is not possible because there is no IQ DAC to do that. Is there a (firmware) workaround that can be implemented for this? Maybe some transformations to the IQ samples before feeding them back to the RF part? In other words, how to translate IQ samples to feed them into the synth for TX.

If not, can you recomment another TI SoC that can accept IQ samples for transmission? SubGhz bands.

Thanks!

This is not supported on CC1310 or on any of our other radios.

CC1260 is a possibility: https://www.mouser.com/catalog/specsheets/txii-s-a0011474260-1.pdf

The support for this part is very limited though.

Very good, thanks! This is almost the part that I am looking for.

Now I only need to check if there is one that covers most of subghz subbands (including 434 MHz) because CC1260 is only for the upper side of subgzh band.

Nevertheless CC1260 has the functionality that I am looking for, both RX and TX using IQ signals.
