What type of operation does the mixer perform?
does it perform complex multlipication?
can u attach the snap of the spectrum and explain the general 3 port mixer behaviour with IF and LO inputs to result an rf output?
Hi SIR Please provide the AD9361 Reference spectrum For QPSK modulated signal.
we getting the spectrum but it is correct or not we are not concluding
please confirm sir we are generating IQ qpsk modu…
were you able to demodulate the waveform in spectrum analyzer and measure the EVM
yes if keep the tone frequency as 2 MHz even in Matlab or baseband DDS.
Can you please specify to which product are you referring, if you have any questions about AD936X please post here?
For general basics refer to the below link for your question.
Below are things need to do before porting data into AD9361. for the waveform in your case it is QPSK, first, verify the waveform at baseband level and plot the digital data, once you are satisfied with IQ data in the simulation, port the same things in AD9361 and check the performance. Please make sure to keep the data rate for the AD9361 same as the waveform.
we can't support custom-based design, and users need to validate the waveform and conclude the characteristics.
Attached is the example QPSK waveform file, use this for evaluation.
