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?
