AD9364 Tx Output Power

Hi.

 

I am using Ad-fmcomms4 and AC701 boards. In my test project I have excluded AuxDAC, AuxADC. All of the received data are sending to transmitter.

 

Nowadays, I am using all of the configurations like in GitHub project:

(BBPLL freq = 4*ADC_CLK = 8*DAC_CLK= 98304000 Hz

Rx RFPLL freq = Tx RFPLL freq = 2400000000 Hz

Rx RF BW = Tx RF BW = 18000000 Hz

Tx Attenuation = 10dB

and other)

 

After the initialization, I saw that Tx Power in my project is lower than in GitHub project. The difference is 15dB.

I have checked almost all of the registers, but all of their values are equal (except "Tx Quad Calib result" registers).

 

Can you tell me, please, how to control the tx output power level?  How to make it higher?

 

P.S. I'm sorry for my English, I hope that I was able to explain my problem to you.
