Part Number: CC1120EM-169-RD
Other Parts Discussed in Thread: CC1120

Hello,

I am interested in employing the CC1120 for a 169MHz telemetry application.

Is the 169MHz band legal for use in the USA by the FCC?

Also, does TI make a product for 27MHz?

Thanks,

Hi Jay, 169 MHz is not a license free band in USA. It might be possible to buy license a frequency here, but we have not investigated this. In the US, most of our customers use the 902-928MHz band. TI does not have integrated RF products that covers 27 MHz. 27 MHz products was used in toys and low RF range products, but this has to a large extent been replaced by 2.4 GHz solutions (BLE and proprietary). We have some "soon to come" new products that can be used to solve these applications, see more here: https://news.ti.com/new-bluetooth-le-wireless-mcus-make-high-quality-rf-and-power-performance-more-affordable

engiNerd,

You may be aware that 915MHz and/or 2.45MHz have TERRIBLE range when installed just level with or slightly below ground.

Yes, I do understand the vast majority of applications utilize those frequency bands.

Those have already been tried without success.

I was hoping for a TI solution:-(
