1.首先校准参数要改:
[Frequency Bank]
bank = 0x12
;bank = 0x1E
;bank = 0x1C
;bank = 0x1C
; GSM450 0x01
; GSM850 0x02
; GSM900 0x04
; DCS1800 0x08
; PCS1900 0x10
2.AFC校准频段要改
[AFC Calibration]
;AFC_BAND: GSM, DCS, PCS, GSM850
AFC_BAND = GSM850
AFC_ARFCN = 190
N_AFC = 10
DAC1=4000
DAC2=5000
CRYSTAL_DAC1=3800
CRYSTAL_DAC2=4200
3.Crystal校准频段要改
[Crystal AFC Calibration]
;CRYSTAL_AFC_BAND: GSM, DCS, PCS, GSM850
CRYSTAL_AFC_BAND = GSM850
CRYSTAL_AFC_ARFCN = 190
4.我想你说的软件要改是指 下面的地方
#define Custom_RF_XO_CapID 66 //48
/*MTKSOC1*//*----------------------------------------------*/
/*MTKSOC1*//* 0:GSM850 Signal go through GSM850, GSM900 Signal go through GSM900 (default) */
/*MTKSOC1*//* 1:GSM850 Signal go through GSM900, GSM900 Signal go through GSM850 (default) */
/*MTKSOC1*//*----------------------------------------------*/
/*MTKSOC1*/#define GSM850_GSM900_SWAP 1
/*MTKSOC1*//*----------------------------------------------*/
/*MTKSOC1*//* 0:DCS1800 Signal go through DCS1800, PCS1900 Signal go through PCS1900(default) */
/*MTKSOC1*//* 1:DCS1800 Signal go through PCS1900, PCS1900 Signal go through DCS1800 */
/*MTKSOC1*//*----------------------------------------------*/
/*MTKSOC1*/#define DCS1800_PCS1900_SWAP 1
如果 850和900需要交换 ,则为 1;无需交换则为 0.
1800/1900 同理。
希望对你有帮助 |
