AD9364 products Tx single-carrier with a lot of clutter and low transmitting power.

I am debugging the AD9364. AD9364 provides a 800MHz LO, and FPGA provides a 1MHz data single from BBP. I aim to get a 801MHz Tx single-carrier. Two problems occured.


One is the transmitting power I  get is -12dBm with 19dB attenuation, but get -34dBm with 0dB attenuation. Why I set up larger attenuation and get a  larger power?


The other is the spectrum of the Tx single is mussy, with a lot of clutter. I provide a picture attachment.
