Embodiment Construction
[0017] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.
[0018] Such as figure 1 As shown, the present invention provides a walkie-talkie, including a walkie-talkie body, the walkie-talkie body has a shell, and an MCU controller 1, a baseband processor 2, a high frequency divider 3, a MIC microphone 4 and a loudspeaker integrated in the shell Speaker 5. The walkie-talkie body receives and sends signals through the antenna. The MCU controller 1 is bidirectionally connected to the baseband processor 2 and the high-frequency divider 3 respectively, and the antenna is connected to the input end of the baseband processor through a low-pass filter, a TX / RX switching module and a high-frequency amplification module in turn, and the antenna It is also connected to the input terminal of the high-frequency divider through a low-pass filter. The output end of the MCU control...
