Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
At first consult Fig. 1, Fig. 1 is the electrical block diagram according to the mobile phone of first embodiment of the invention.As shown in Figure 1, mobile phone of the present invention comprises radio-frequency power amplifier 201, range sensor 202 and base band signal processing chip 203.Wherein, Base band signal processing chip 203 is connected with radio-frequency power amplifier 201, is used to be provided with the maximum power output valve of radio-frequency power amplifier 201, and; Base band signal processing chip 203 is connected with range sensor 202, is used to obtain the interrupt signal that range sensor 202 produces.
In the present embodiment, utilize base band signal processing chip 203 that the peak power output of two parameters with control radio-frequency power amplifier 201 is set.Wherein, parameter is the parameter that is provided with of radio-frequency power amplifier 201, is used to set the peak power output of radio-frequency power amplifier 201.And in the present embodiment, be 560 through first parameter is set, first power output that is used to control radio-frequency power amplifier 201 is 32dBm, and it is 580 that second parameter is set, and second power output that is used to control radio-frequency power amplifier 201 is 33dBm.
Because when doing the phantom test; Need press close to people's face tests; Therefore; Utilize range sensor 202 detection of handset whether near people's face, thereby when determining mobile phone, send interrupt signal to base band signal processing chip 203, make base band signal processing chip 203 that radio-frequency power amplifier 201 is set and make it with bigger peak power output output radiofrequency signal near people's face.
And; Because phantom test is under the situation of the peak power output grade of radio frequency, to test, therefore when carrying out the phantom test, in case set up conversation; The base station can be sent a maximum power to mobile phone and sent instruction; The order mobile phone is exported radiofrequency signal with peak power output, therefore, and when the maximum power of not receiving the base station is sent instruction; Show that not be to carry out the phantom test this moment, power demand output radiofrequency signal when this moment, base band signal processing chip 203 control radio-frequency power amplifiers 201 were with normal talking.
When base band signal processing chip 203 receives maximum power transmission instruction; Base band signal processing chip 203 further judges whether to receive the interrupt signal of range sensor 202, and when not receiving interrupt signal, base band signal processing chip 203 adopts first parameter 560; Peak power output with control radio-frequency power amplifier 201 is the first power output 32dBm; In this case, aerial radiation power can reach 28.2dBm, reaches standard.
When base band signal processing chip 203 receives the interrupt signal of range sensor 202, thereby because the phantom test need make range sensor 202 produce interrupt signals near people's face mobile phone, in this case; Decidable is current to carry out the phantom test, so adopt second parameter 580, second power output of control radio-frequency power amplifier 201 is 33dBm; Therefore; When test phantom,, make peak power output improve 1dBm because radio-frequency power amplifier 201 adopts the second power output 33dBm as peak power output; Data when having increased the phantom test, thus realize promoting the phantom antenna performance.
Below will introduce the power regulating method of mobile phone of the present invention referring to Fig. 2 more full and accurately.
