Dear Sir,
Attached please find the 2nd harmonic we found in CC8530 pre-scan. Previously, we make pre-scan does not find the problem that we have 4-5 dB margin. it is under Rx mode
Now, we found that 2nd harmonic is failed 2 dB in headset and pass about 7 dB in base. The failure is due to the emission at frequency offset to the 2nd harmonic as in attachment.
Any advise? what kind of schematic design and PCB layout we need to consider
B.R.
Edwin
