There are broad spread spurious emissions in the vicinity of transmit channel in IEEE802.15.4g packet with GFSK TX filter.
In Generic packet, there are two kinds of results according to the TX filter. With GFSK TX filter, there aren't any abnormal spurious emissions. But with FSK TX filter, there are similar spurious emissions as in IEEE802.15.4g packet with GFSK TX filter.
Are there any appropriate registers to suppress spurious emissions?
