Analysis on the RF Interference in GSM/CDMA 1X Dual-mode Terminals

摘要：

This paper is to study on the RF design of GSM/CDMA IX simultaneous dual-mode mobile terminal. First,considering government regulatory requirements,the main RF interference between GSM and CDMA IX unitsInthe terminal and the required C/N at CDMA unit input for the receiver normal operation is analyzed. Secondly,the C/N at CDMA receiver input under the cases of Co-channel and adjacent channel interference generated by GSM transmission are calculated respectively. Finally,the solution for suppressing the interference of GSM transmission to CDMA in a GSM/CDMA IX dual-mode Terminal design is given and experiment results are shown. With several methods adoptedInthe real product design,the GSM/CDMA 1X simultaneous dual-mode mobile terminal was successfully developed.
