CC1175: Evaluating at 450-470MHz

Dima Grinko

Part Number: CC1175
Other Parts Discussed in Thread: CC1120

Hi Team,

a customer of mine is currently using the CC1120, and now needs the CC1175 for transmitter uses.

they need to evaluate it at 450-470MHz,12/5KHz channels, but I see there's no EVM for this device at this frequency.

how can the customer do this?

appreciate your help

They need to modify an existing EM for their needs:

- Option 1: Get a CC1175 EM for 868 MHz and modify the BOM to BOM for 450 - 470 MHz

- Option 2: Get a CC1120 EM for the 400 MHz band and modify this to use CC1175.

Both require unfortunately some soldering skills

Thanks.

where can the 450-470MHz BOM be found? (either for CC1175 or CC1120)

Remove the components in the red box, ground where a line is drawn.
