Dear all,

as part of my course i have been asked to design a transceiver (transmitter and receiver circuits) based on QPSK modulation technique using analouge IC components. Can any one help.

if you have any questions please do not hesitate to reply.

thanks for the help

regards

 

Perhaps you cold reverse engineer this:

hi
thank u very much for replying i have had a look at both links, but i have already tied this path and after spending weeks i decided that it will be easier to desing from scratch rather than try and use reverse engineering on these proffesionally designed chips.

if u get any more info please do post it. it will be much appreciated once again thanks
