Abstract
Provided in the disclosure is a dual-mode mobile terminal. The dual-mode mobile terminal includes: a CMMB antenna embedded in the dual-mode mobile terminal; a CMMB protection network connected to the CMMB antenna, comprising multiple stages of circuits connected successively, wherein each stage of circuit in the multiple stages of circuits is an LC series circuit or an LC parallel circuit, two ends of the LC parallel circuit are connected between the stages of circuits before and after the LC parallel circuit, and one end of the LC series circuit is connected between the stages of circuits before and after the LC series circuit, and the other end of the LC series circuit is grounded. According to the technical solution provided by the disclosure, the interference problem among multiple antennas in the CMMB antenna embedding solution in the related art is solved, thus being able to reduce the interference to CMMB signals by multi-mode radio frequency signals.
