TIDA-00374: Temperature and humidity sensor node based on CC2650

steffi george

Part Number: TIDA-00374

We are using TIDA00374 TI reference design and in this PCB Gerber file "tidc949a", impedance control information related to antenna and RF section is not included in the Gerber file. Would you please share it?

Hi steffi,

I've reached out to one of the TI Design authors, however given the age of this reference design I would not expect that this information can be provided.

Regards,
Ryan

While I'm not a design author, I can see that the design follows about what I'd expect from our design guide considerations document. What specific details are you looking for?

An appropriate 50 ohm trace width can be calculated by downloading the TXLINE software free online.

The antenna information can be found here.

It seems they were able to match their antenna with a single shunt component (C27). If you're looking to mimic the design, I would recommend using a Pi network to give yourself more flexibility in antenna matching.
