Is the TX output a combination (sum) of the I and Q components, or does it output only the I component or only the Q component?
Additionally, is the TX output converted into TX+ and TX− by the balun, or by other components?
Thank you for your answers. I have a few additional questions:
Are the signals at points 1 and 2 the I and Q components, respectively, or is it the opposite?
Are the signals at points A and B identical?
How do the signals at A and B become TX2+ and TX2−? In other words, how are they converted into differential signals?
Is there a phase difference between the output signals TX2+ and TX2−? If so, is the phase difference 180 degrees?
Please refer to UG-1727 for more details. The differential TX output is analog domain, which means 180 degree difference. The I and Q paths are combined using IQ mixer.
Thank you very much for your responses and support. We really appreciate your help.
We have studied UG-1727 in detail; however, we still have a few questions:
Is the signal at point 1 SERDINAB+ or SERDINAB−? Is this configurable?
Is the signal at point 3 obtained by multiplying the signal at point 2 with a cosine waveform or a sine waveform? Is this configurable?
Thank you in advance for your time and clarification.
1A) Yes, this is configurable. I guess you are asking about swapping P and N. You can change in the profile.
If there is a PN swap, make the below highlighted parameter 1 in the JSON.
2A) It does not matter. you can not configure it.
