CC1310: Reference design for 400 MHz Band

Hi TER,

1. Can I use “CC13xxEM-7XD-4251_schematic_1_2_0.pdf” as a reference design for CC1310 at 400 MHz.
2. Will the LC balun cause any performance degradation at 400 MHz?
3. Is there any design file for Single ended operation at 433MHz/400 MHz ?

Thank you in advance for any help you provide.

1) Yes. You may need to scale the components a bit. I would first test @400 MHz with the 433 MHz BOM. Then you can scale the components with a 400/433 factor and see if you get any better result.  

3) http://www.ti.com/lit/an/swra528/swra528.pdf could be used as a starting point. 

Thank you TER,

Thanks for the reply.

What is the single ended impedance seen on the RF pins at 400 MHz ?

We have not measured this and have no plans doing so.

Ok
