LP-CC1311P3: Can LP output frequencies besides 868-915MHz?

Hi,

As you point out, you can refer to Section 8.9 of the CC1311P3 Datasheet: https://www.ti.com/lit/swrs255 to find a list of the possible frequency bands that the CC1311P3 is compatible with.

However, the LaunchPad is optimised for operation in the 868/915 MHz bands so you would need to manually modify the BOM of the RF path for acceptable performance at the other frequency bands.

What we would currently recommend is evaluating the performance of one of the other CC13xx LaunchPads that are optimised for operation at 433 MHz (for example the LP-CC1352P7-4: https://www.ti.com/tool/LP-CC1352P7 ). The CC1311P3 was actually characterised on the LP-CC1352P7-4 platform for 433 MHz operation (the datasheet will be updated to correct this).

So, if you are mainly interested in the radio performance only you can just evaluate the LP-CC1352P7-4 as-is because the radio performance is comparible. Alternatively you could mount a CC1311P3 onto a LP-CC1352P7-4 as it is pin-pin compatible.

Yes, you can evaluate this using SmartRF Studio 7: https://www.ti.com/tool/SMARTRFTM-STUDIO

It has a range of output power settings, from +13 dBm to -11 dBm.
