The homologation requirements in China (MIIT [2002]353) obviously are planned (end of December 2022) to be sharpened (MIIT publication from 2021-01-27:
“Notice on Matters Related to Radio Management in the 2400MHz, 5100MHz and 5800MHz Bands”).
A modification register is need on the KW38 and KW36 to pass the new Chinese requirement with acceptable margin:
PA_RAMP_SEL value must be set to 0x02h (2us) instead of 0x01h (1us default value)
Modification SW: XCVR_TX_DIG_PA_CTRL_PA_RAMP_SEL(2) in the nxp_xcvr_common_config.c
All the details are in the attached file.
Note: This SW modification is for China country only.
