CC2652P: Does CC2652P power ampliflier affects reception quality?

Part Number: CC2652P
Other Parts Discussed in Thread: CC2652RB, , CC2652R

Tool/software:

Hello,

I'm planning to use CC2652. It comes in 2 versions CC2652RB and CC26R2P. The last one provides a +20dBm power amplifier.

My guess is that the amplifier operates only for transmission and not for reception but I'm not fluent in radio and I imagine that it could provide amplification and filtering also on the reception side.

Please can you confirm which assumption is the right one?

Thanks

Julien

    Hi Julien,

    The PA is only for amplifying the Tx signal.

    A Low Noise Amplifier (LNA) would be used to amplify an Rx signal; the regular 2.4 GHz radio contains both a PA (+5 dBm) and LNA internally. The CC2652P contains both the regular 2.4 GHz radio, used for Rx operation and Tx operation for power levels up to +5 dBm, and the +20 dBm PA. The CC2652R contains only the regular 2.4 GHz radio.

    Regards,

    Zack
