           The calculated SNR for given integrated phase noise @ the frequencies above 5GHz is 39 dB and the transmitter EVM of the AD9364 is 36 dB ... from this understands,the EVM of the transmitter involves  LO phase noise .

           Does  it possible to improve phase noise of the LO's in the AD9364 evaluation board  though it  improves  transmitter EVM?please suggest us how to improve the LO phase noise in the ad9364 evaluation board.

           The higher modulation like 64 QAM requires 27 dB SNR  @1e-6.. To achieve this the QAM transmitter should be at least 10 dB more of required SNR of 27dB. please comment on this.
