Embodiment
See also Fig. 1, the utility model realizes that the repeater of module backup comprises near-end (base station end) duplexer 1, far-end (mobile you) duplexer 1 ', between near-end duplexer 1 and far-end duplexer 1 ', comprise up link and down link, generally include several radio-frequency module groups 2 in each link, in order to finish such as frequency-selecting, down-conversion, up-conversion, processing such as power amplification, mainly being based on the downlink or uplink signal handles in radio-frequency stage, therefore, radio-frequency module group 2 includes but not limited to the frequency-selecting module, down conversion module, the up-conversion module, low noise amplifier, radio-frequency signal processing devices such as power amplifier.
The donor antenna of repeater is after be coupled to downlink radio-frequency signal in the air, be forwarded in the down link through near-end duplexer 1, after the radio-frequency module groups 2 at different levels of flowing through are carried out signal processing, be forwarded to cover antenna through far-end duplexer 1 ' again, outwards launch until travelling carriage by cover antenna; Otherwise, after cover antenna receives the upward signal of travelling carriage, transmit up link through far-end duplexer 1 ', after multi-level radio-frequency module group 2 is carried out signal processing, be forwarded to donor antenna through near-end duplexer 1 again, send to the base station by donor antenna and finish up process.In up link and/or down link, also can use other base band level processing module that up and/or downstream signal are handled accordingly in case of necessity, because of belonging to known technology, this not all right giving unnecessary details.
The utility model realizes that the principle of backup is based on each radio-frequency module independently backed up and carries out that specifically as shown in Figure 1, each radio-frequency module group 2 comprises 23,23 ', distributor 21 of duplicate radio-frequency module and a synthesizer 22 on two functions.Distributor 21 is used in signal allocation to two radio-frequency module with link, and generally adopting phase difference is the 3dB electric bridge power dividers of 90 degree; Synthesizer 22 in like manner, also can adopt phase difference be 90 the degree 3dB electric bridge power combiners.The lectotype selection of distributor 21 and synthesizer 22 is not subjected to the restriction of power divider and power combiner, accordingly, the type selecting of power divider and power combiner also should not be subjected to the restriction of 3dB electric bridge, to disclose another embodiment of the present utility model below, illustrate that synthesizer 22 adopts the situation of another implementation.Therefore, those skilled in the art can become suitable power divider or power combiner by selecting different equipment disposition for use.
90 degree 3dB electric bridges are during as power divider 21 and power combiner 22, uplink/downlink signals is dispensed to two radio-frequency modules 23 of radio-frequency module group 2 by the 3dB electric bridge of making distributor 21, in 23 ', two radio-frequency modules 22, signal phase in 23 ' differs 90 degree, when radio-frequency module 22,23 ' uplink/downlink signals finished corresponding processing after, again by the 3dB electric bridge of power synthesizer 22 with two radio-frequency modules 22,23 ' signal synthesizes one road signal, does further processing in the feed-in Uplink/Downlink.
Under the situation of repeater operate as normal; 3db electric bridge power divider 21 and power combiner 22 and two radio-frequency modules 23; 23 ' application; increase 3dB in the time of making output 3 rank point of cut-offs (OIP3) with respect to use single radio frequency module; but; when one of them radio-frequency module lost efficacy, the gain of circuit about 6dB that can descend usually.
In up and/or down link, can back up each radio-frequency module 23,23 ' according to actual needs, can incremental backup, but also full backup, on the specific requirement of repeater reliability is decided.
See also Fig. 2, further disclose the legend that radio-frequency module group 2 described in the utility model adopts another mode to realize.Different with a last embodiment is that the synthesizer 22 in this enforcement adopts the alternative radio-frequency (RF) switch to replace.When certain radio-frequency module (as 23) when breaking down, the signal in this radio-frequency module group 2 is by another one radio-frequency module (then 23 ') individual processing, and alternative radio-frequency (RF) switch 23 ' automaticallyes switch and connects the radio-frequency module of this operate as normal.In the present embodiment, no matter whether fault, and the output 3 rank point of cut-offs (OIP3) of radio-frequency module group 2 are to equate substantially when adopting the single radio frequency module, and unique to need the factor of consideration be the loss of radio-frequency (RF) switch, but less because of its value, so can ignore.When a radio-frequency module in the radio-frequency module group 2 broke down, the gain of circuit can remain unchanged.
In like manner, described synthesizer 22 also can adopt relay switch to replace, and can realize the function of alternative.
