MATLAB: How to Enhance AD9361 Transmission Power using Support Package for Xilinx Zynq-Based Radio

Question

Hi. I checked the datasheet for 9361, which has a maximum output power of 7.5 dbm in the 2.4GHz band, but actually when I call the sdrtx() function of the zynq-based radio support package with the Gain parameter set to a maximum of 0, and the transmit power still does not reach the required strength, the actual power is about 5 dbm or less.

Sw: Matlab19b + support package for Xilinx Zynq-Based Radio

Hw: Zedboard (Xilinx Zynq – 7000) + AD9361

So how can I enhance the transmition power? Maybe by setting some parameters or editting the config file in FPGA?

Thanks.

Code:

sdrTransmitter = sdrtx('AD936x', ...
    'Gain', 0);

Hi Ivan,

The MathWorks support package operates through ADI drivers, and this being a hardware question, it would be better directed at ADI. You can post the question on their Software Interface Tools forum on ADI Engineer Zone.

Thanks,
