A GSM/CDMA dual-mode mobile phone and a method for inhibiting GC interference are provided. The phone has a dual-port antenna(4) respectively connected with a duplexer(l 3) and a GSM radio frequency circuit(2) to access GSM and CDMA signals. A radio frequency switch(114) is configured in CDMA radio frequency receiving circuit(ll), which is controlled by a GSM base band chip(32), and is utilized for cutting down the CDMA signal accessed by the dual-port antenna(4) during an emitting time slot of the GSM, and when GSM working frequency and CDMA working frequency are in a near frequency band. The phone of the invention inhibits the interference of GSM emission from impacting on CDMA reception, thus simplifies the antenna designing. |
