To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
In order to preferably adapt to the development of microwave communication, user wishes either still to carry out short haul connection in progress long haul communication, and microwave telecommunication devices can ensure the preferable service quality of user；General, user is when carrying out long haul communication, and the power output of microwave telecommunication devices is larger, and when user is carrying out short haul connection, the power output of microwave telecommunication devices is smaller.Therefore, in order to provide the user with more preferable service quality, typically all for different communication scenes, using different microwave telecommunication devices.This is inadequate mainly due to the dynamic range of microwave telecommunication devices power output, i.e. when user carries out long haul communication, microwave telecommunication devices provide high-power scope, but when user carries out short haul connection, if microwave telecommunication devices continue to provide the user high-power output, system capacity can be brought to waste；Or when user carries out short haul connection, microwave telecommunication devices provide small-power output, but when user is changed into long haul communication from short haul connection, the power that microwave telecommunication devices are now provided just is difficult to ensure that the communication quality of user.
If therefore the output power range of microwave telecommunication devices is sufficiently large, it is possible to while long haul communication and the short haul connection of compatible subscribers, it is ensured that the communication quality of user.
The structure of the lifting device embodiment one for the output signal power scope that Fig. 1 provides for the present invention is shown
It is intended to, the device can be arranged in microwave telecommunication devices, and the device can be 0DU.As shown in figure 1, the device includes：Judge module 10, triggering generation module 12, the second triggering generation module 13 of processing module 11, first and output module 14;Wherein, judge module 10, for judging that the power of signal to be output is located at the first power interval or the second power interval；Wherein, the signal to be output is the signal for meeting user power demand；Processing module 11, carries out the first power attenuation, and the input signal after decay is divided into the first power signal and the second power signal according to predetermined power allocation proportion for the input signal to described device；First triggering generation module 12, if the power for judging signal to be output for above-mentioned judge module 10 is located at the first power interval, the second channel that then triggering is closed where the second power signal, and the first power signal is carried out after the first processing, generate signal to be output；Second triggering generation module 13, if the power for judging signal to be output for above-mentioned judge module 10 is located at the second power interval, the first passage that then triggering is closed where the first power signal, and the second power signal is carried out after second processing, generate signal to be output；Output module 14, for exporting above-mentioned signal to be output.
Specifically, when user needs microwave telecommunication devices output to meet the signal of its power requirement, this signal is signal to be output, judge module 10 can judge that the power of the signal to be output is located at the first power interval or the second power interval first, here the first power interval and the second power interval can partly overlap, can not also be overlapping；After judge module 10 carries out power judgement, the input signal of 11 pairs of devices of processing module carries out corresponding first power attenuation, and the numerical value of the first power attenuation can be determined by the power of signal to be output here；Also, the input signal after decay is divided into the first power signal and the second power signal by processing module 11 according to default power sharing ratio.
When above-mentioned judge module 10 judges that the power for obtaining above-mentioned signal to be output is located at the first power interval, the second channel that then the first triggering triggering of generation module 12 is closed where the second power signal, and the first processing is carried out to the first power signal, generation meets the signal to be output of user power demand and exported；Here carry out first to the first power signal to handle, can include handling decay again, power amplification of the first power signal etc.；When above-mentioned judge module 10 judges that the power for obtaining above-mentioned signal to be output is located at the second power interval, the first passage that then the second triggering triggering of generation module 13 is closed where the first power signal, and second processing is carried out to the second power signal, generation meets the signal to be output of user power demand and exported, here second processing is carried out to the second power signal, can includes handling power amplification of the second power signal etc..
With the difference of user power demand（User may require that the signal for exporting different size of power）, said apparatus can export the signal of different capacity.
For example：It is assumed here that the first power interval is [0dBm, 25dBm], second power interval is [- 20dBm, OdBm], it is assumed that user wishes to export the signal in the range of 12dBm_24dBm, then the device can judge which power interval the power of those signals to be output is located at using judge module 10.According to judgement, the power of those signals to be output is located in first interval, then input signal of the processing module 11 now to the device carries out the first power attenuation, as for the input signal to the device power attenuation how much, it can be by the watt level of 11 pairs of input signals of processing module, the watt level and power sharing ratio of signal to be output carry out considering determination, that is when input signal is after the first power attenuation, and the signal power by predetermined power pro rate to first passage is after first is handled, the signal for the power that user wants can just be exported.Also, input signal is distributed to first passage and second channel in processing module 11, the first triggering generation module 12 can now trigger closing second channel, realize the energy isolation of two passages.Finally, the device can just export the signal in the range of 12dBm-24dBm.
Assuming that user now also needs to the signal in the range of output-lOdBm-OdBm, likewise, the device can judge which power interval the power of those signals to be output is located at using judge module 10.According to judgement, the power of those signals to be output is located in second interval, then input signal of the processing module 11 now to the device decays, as for the attenuated input signal to the device how much, also it can be by the watt level of 11 pairs of input signals of processing module, the watt level and power sharing ratio of signal to be output carry out considering determination, that is when input signal is after this decay, and the signal power by predetermined power pro rate to second channel is after second processing, the signal for the power that user wants can just be exported.Also, input signal is distributed to first passage and second channel in processing module 11, the second triggering generation module 13 can now trigger closing first passage, realize the energy isolation of first passage and second channel.Finally the device can just export the signal in the range of -10dBm-0dBm.
But in the prior art, when user wishes to export 12dBm-24dBmIn the range of signal, prior art can meet user's requirement, but when user wishes that microwave telecommunication devices can also export the signal in the range of-l OdBm-OdBm, due to lacking the processing branch of the second power interval and second channel in the prior art, then the signal in the range of-lOdBm-OdBm cannot be exported.
The embodiment of the present invention provides a kind of lifting device of output signal power scope, judge that user requires that the power of the signal to be output of output is located at the first power interval or the second power interval by judge module, processing module is carried out after the first power attenuation to the input signal of described device according to predetermined power allocation proportion point

Specifically, when the power of the output signal required by user is different, then decay of the processing module 11 to input signal in said apparatus is different.The value of above-mentioned first power attenuation is determined by the watt level of the input signal of the power of signal to be output, the ratio that predetermined power is distributed and said apparatus.
