The ADF4158 can be used as PSK modulator ,but the phase is only changed between 0 and 180,which meanings BPSK. Now I want to use a PLL as QPSK or 8PSK modulator,how can I do that?
It is possible to use the ADF4350 for PSK modulation. It will allow you to implement QPSK without the need for an DAC + I/Q modulator.

Sorry, I have a question: is it possibile to use a DSS module to obtain the same modulation with a carrier output frequency of 5 kHz?
What does DSS stand for? I don't think that any of our PLLs can operate at a 5 KHz carrier frequency.
Sorry again, DDS and not DSS!! ...I sent an email to your colleague of analog device (Bernhard Siegel), and I asked to him, if I could use a DDS to have a sinewave with carrier frequency at 5 kHz...and he answered yes:
"On the Web Tool I selected the AD5930 as a DDS sufficient for a 5Hz output" ...but I have also to implement a DPSK modulation. Thus, I need a device able to give me a possibility to do both things. What do you think about this? ...Can I use AD5930 to do it?
Moving this to the DDS community since the discussion has moved on the AD5930.
Retrieving data ...
