Suggest me best transceiver

Please look at the CC1352P or CC1354P chips.

Hi Aman,

None of our transceivers have an integrated +20 dBm power amplifier - you would need to include an additional FEM module for this. The maximum output power possible with our transceiver products without an external amplifier is +16 dBm.

Our CC13xx "P" SoC devices have an integrated +20 dBm power amplifier. You can evaluate which of these meet your requirements for cost, flash size, device size, ect.

You can see an overview of our SoCs on the following TI.com page: https://www.ti.com/wireless-connectivity/sub-1-ghz/wireless-microcontrollers/overview.html 

Most applications at 433 MHz require +10 dBm or +13 dBm due to regulatory requirements, so please double-check your output power needs for this band.

Regards,

Zack
