3.10 H/W Sub System
3.10.1 RF Interface
A. RTR6250 (WCDMA_Tx, GSM_Tx/Rx)
MSM6250A controls RF part(RTR6250) using these signals.
• SBST,SBDT,SBCK : SBI I/F signals for control Sub-chipset
• PAON : Power AMP on RF part
• RX_I/Q,TX_I/Q : I/Q for T/Rx of RF
• TX_AGC_ADJ : control the gain of the Tx signal prior to the power amplifier
