HANDSET DEVICE, HANDSET, AND METHOD FOR PROCESSING SIGNAL BY USING HANDSET DEVICE

摘要

Disclosed are a handset device, a handset, and a method for processing a signal by using a handset device. The handset device comprises: a first interface, a second interface, a switch, and an isolation unit. The isolation unit comprises a first isolation body and a second isolation body connected to the first isolation body in parallel. The first interface is connected to the second interface through the isolation unit. The first interface is configured to be connected to a ground network of a handset. The second interface is configured to be connected to a ground line of a mobile terminal where the handset is located. The first isolation body is configured to block a signal coupled to a frequency modulation range of the ground network. The second isolation body is configured to block a signal coupled to a cellular communication frequency range. The switch is configured to select to connect the first isolation body, the first interface, and the second interface, or select to connect the second isolation body, the first interface, and the second interface. Through the present invention, when TDD noise interference is reduced, FM interference also needs to be reduced, thereby improving the user experience.
