Abstract
A GSM/PHS dual-mode mobile phone adopting a single antenna includes an antenna separately connected to a GSM module and a PHS module through an antenna module, and the antenna module is connected to a central processing unit for receiving a control signal transmitted from the central processing unit to switch its connection between the modules, so as to select the GSM or PHS operating mode and carry out the detection and transmission of a signal with a frequency of 900 MHz or 1900 MHz at the GSM or PHS operating mode.
Claims7
A GSM/PHS dual-mode mobile phone adopting a single antenna, comprising:
- a central processing unit controlling related components and circuits in said dual-mode mobile phone to operate in a normal condition;
- a GSM module coupled to said central processing unit for transmitting and receiving a signal at a GSM mode of said dual-mode mobile phone;
- a PHS module being coupled to said central processing unit for transmitting and receiving a signal at a PHS mode of said dual-mode mobile phone;
- a single antenna;
- an antenna module being separately coupled to said central processing unit, said GSM module, said PHS module and said single antenna for switching a connection status between said antenna module and said GSM and PHS modules according to a control signal transmitted from said central processing unit so as to set said dual-mode mobile phone to a GSM operating mode or a PHS operating mode, thereby enabling said dual-mode mobile phone to detect, transmit and receive a signal of a frequency used in the GSM operating mode or the PHS operating mode.
