I only kown that the I Q singnal need the same width and the same length when PCB layout ,but I still don't konw the best width and space between I Q Singal ?
Does anybody who can give me some ideas?
many thanks !!!
 

IQ signal shall be ground protected.
IQ signal can be 4mil width with 4 or 8 mil spacing in between
IQ signal shall be at least 8 mil away from other signals and 4mil minimum
distance to enclosure ground.

8PSK modulation IQ would be much concerned and sensitive to layout defect
than GMSK modulation
 
Check the tranceiver's differential input impedance,
then you can use tool(like POLAR) to calculate the width and space between I Q base on your PCB stack up.
Please keep the width wider (at least 4mil) for PCB varation and impedance control.
