Hi everyone,

I have designed a simple QPSK transmitter to test the ACPR and EVM of my PA.

However, I have some trouble with the component VtLFSR_DT in ads. (**broken link removed**)

Apparently the taps and seed will affect my results and I am still lost after looking at the guide as I am an RF guy.

Could someone please let me know what sort of values should i put in them for my simulation?

And in the event that if it is a BPSK, how should i go about doing it? changing the tstep to 1/(1*symbolrate)?

Thanks for the advice in advance

Aaron
