CC1120: About the Reference Design of 205MHz - 240MHz

We plan to test CC1120 working in 205MHz - 240MHz freq bands recently.

We found the message below in SWRS112H - CC1120 High-Performance RF Transceiver for Narrowband Systems Page 7.

Could you provide any suggestion or document about the freq bands? Such as tidr227 - RF Layout Reference Design for 420-470 MHz (CC1120) Schematic.

Thanks.
