Distorted AD9361 Tx signal

Category: Software
Product Number: AD9361


In our design we use AD9361 devices that transmit and receive in both channels.

We are feeding the AD9361 Tx channel by a “clean “ pulse train.

Observing the AD9361 Tx output (2.94GHz) we see that the signal is somewhat distorted.

Output signal is comprised of input signal to AD9361 (marked in a circle) and running distorted replica of input signal.

Do you have any idea what can cause this effect?
