Hi Team,
My customer uesd cc2642 in their product .But they found the loss of Tx power is too large(set the device output 5dbm and the frequency spectrograph just received 3dbm ) . Can you give some suggestions to improve the tx power.
Ps.
1.The TX power test point is in test point A and has remove the pi-filter circuit or antenna match circui .it can exclude that the loss power is caused by neither pi-filter circuit or antenna match circuit
2. The circuit of diffenenct to single is the same as TI reference design.
3.The following picture is their sch and pcb
