AWR1642: Beamforming of AWR1642

Part Number: AWR1642
Other Parts Discussed in Thread: , MMWAVE-DFP, AWR1243

Hello,

I have two questions for beamforming of AWR1642.

1.To realize beamforming, can we use txPhaseShifter and txOutPowerBackoffCode of profileCfg in "MMWAVE SDK User Guide"?
  Also, what API is corresponded to these settings?
  I can find the rlChirpPhShiftPerTx_t for txPhaseShifter; however, I cannot find API for txOutPowerBackoffCode.
  I'm checking mmwavelink's doxyzen.

2.In the following thread, PhaseShifter is not applicable for xwr1642.
  e2e.ti.com/.../2352283
  Is this a restriction for AWR1642 not AWR1642BOOST?
  API of txPhaseShifter cannot use for AWR1642?
  If this restriction is for AWR1642, is there any release plan of device which is supporting the beamforming in the future?

Best Regards,
Nomo

    Hello Nomo-san,

    A1: The "txOutPowerBackoffCode" is parameter that is part of the profile configuration. You can configure the "txOutPowerBackoffCode" in the profile configuration and use the profile config API (rlSetProfileConfig) to set the value to the device . You can refer to the Radar Indertace control document in the MMWAVE-DFP for further reference.

    A2: The phaseshifter is applicable only for the AWR1243 configuration. This is mostly for the AWR1243 cascade configuration usecase.
    TxPhaseshifter is not supported for the xWR16xx .

    Thanks,
    Raghu
