nRF52 Radio Performance and adaptive regulator control

Why does the nRF52 only have +4dB output when most competitor chips are atleast +6dB (some up to +10dB). I understand that the RX has been improved by 3dB for a better overall link budget, but for beacon applications Tx rules. Is there any plan to release a higher power Tx version?

Looking over the new chip it seems the nRF52 has Adaptive Regulator Control. Does this mean it can smartly switch between internal LDO and external DCDC depending on current consumption?

Thanks,

  • Yes,

    +8dB out of the ST BlueNRG making it a good candidate for beacon applications (though higher in peak currents, the interval of beacon applications make this ok). Not suitable for actual connected applications and the Link budget of a connection isn't as good since there is an inferior TX.

    +7.5dB on the CSR1011. Again much high peak currents, but these are older chips. I was hoping the new Nordic chip would have a comparable max Tx output for beacon applications.

    +5dB CC2640 though in the fine print it looks to be only +2dB once put through a balun.
