Other Parts Discussed in Thread: CC1350

I'm learning CC1350 now, below is the hardware:

and the software is :tirtos_cc13xx_cc26xx_2_20_00_06\examples\IAR\CC1350_LAUNCHXL\rfPacketTx.

I used spectrum analyzer to test CC1350's TX POWER, but the result is -60dBm, apparently it's not correct, but I check the code setting, the RF SW Switch defaults to sub-1GHz path and the External RF Switch is powered on by default. It's wired. And I tried 3 modules at 868M or 433M, the result is the same.

So, any other settings need to midified?

Thanks!

Try to use SmartRF Studio to do TX test again.

hi yikai

Thanks for your reply.

I tried SmartRF Studio to do TX test, the result is the same:-60dBm.

I checked the hardware, and found something strange:

pin1 to pin7 is not breakover, pin8 and pin10 is breakover, pin5 and pin10 is breakover.

pin5 to pin7 is not breakover, pin8 and pin4 is breakover.

Is this result correct?

I guess the normal result maybe is : pin1 to pin7 is breakover, pin8 and pin10 is breakover, and pin5 to pin7 is not breakover, pin8 and pin4 is not breakover.

Do I think right?

The EM is primary an internal development platform. The CC1350 Launchpad (www.ti.com/.../launchxl-cc1350) used the exact same layout and has the same performance as the EM.
