Embodiment
The contrast accompanying drawing elaborates to the utility model in conjunction with embodiment below.
Embodiment one: as shown in Figure 1, a kind of superlinearity multicarrier amplifier, comprise signal distribution unit, forward amplifying unit, forward delay unit, reverse delay unit, reverse amplifying unit, first, second and the 3rd signal synthesis unit, the signal distribution unit input receives extraneous multi-carrier signal, and an output connects forward amplifying unit, first signal synthesis unit and forward delay unit successively; Another output connects reverse delay unit, secondary signal synthesis unit and reverse amplifying unit successively; The 3rd signal synthesis unit two inputs link to each other with the output of forward delay unit with reverse amplifying unit respectively, the extraneous multi-carrier signal of output output after superlinearity multicarrier amplifier is handled; First signal synthesis unit also output signal to the secondary signal synthesis unit.
Principle to superlinearity multicarrier amplifier describes below, and we know, when amplifier amplifies signal, can produce second order inter-modulation signal, third order intermodulation signal etc. simultaneously, and is because these signals are to influence normal signal, therefore the smaller the better.When carrier signal enters superlinearity multicarrier amplifier, by signal distribution unit signal is divided into two-way, one the tunnel is forward signal, amplifies, arrives the 3rd signal synthesis unit through first signal synthesis unit, forward delay unit then through the forward amplifying unit.And another road is the reverse signal processing, at first with input signal by reverse delay unit time-delay phase shift, mix at the secondary signal synthesis unit with forward amplifying unit amplifying signal again and draw the second order inter-modulation signal, the third order intermodulation signal, oppositely amplifying unit amplifies back arrival the 3rd signal synthesis unit again with these signals, mix with the signal of forward amplifying unit through delaying time anti-phase, make the second order inter-modulation signal like this, third order intermodulation signal etc. is offset, thereby reduce the second order inter-modulation signal greatly, third order intermodulation signal etc., make linearity of amplifier better, power efficiency is higher.
Embodiment two: as shown in Figure 2, be with embodiment one difference, the forward delay unit is moved to the reverse signal path by the forward signal path, soon the reverse delay unit of embodiment one and forward delay unit replace with first delay unit and second delay unit among Fig. 2, like this, be different from the phase shift of in forward signal path and reverse signal path, respectively once delaying time respectively in the embodiment one, but twice phase shift of delaying time in the reverse signal path, finishing signal, can guarantee when synthetic forward signal of the 3rd signal synthesis unit and inter-modulated signal the second order inter-modulation signal equally, third order intermodulation signal etc. obtains offsetting.
The invention also discloses a kind of multicarrier amplification system of using one of above-mentioned two kinds of superlinearity multicarrier amplifiers, comprise base station and antenna, the signal distribution unit input is coupled to extraneous multi-carrier signal in the base station, and antenna receives the extraneous multi-carrier signal of output after superlinearity multicarrier amplifier is handled.
As shown in Figure 3, this multicarrier amplification system, can also comprise two duplexers and low noise amplifier, the terminal of closing of two duplexers links to each other with antenna with the base station respectively, superlinearity multicarrier amplifier is connected between a pair of minute terminal of two duplexers, low noise amplifier be connected two duplexers another between minute terminal.
Comprise descending process and up process during system works: A) descending process: the multicarrier input signal that is coupled through the base station enters into superlinearity multicarrier amplifier and handles amplification through diplexer separates, outputs to antenna by duplexer again.B) up process: the signal that antenna receives is through diplexer separates, after entering into low noise amplifier and amplifying, is coupled into the base station by duplexer again.
For plural multi-carrier signal, because each carrier signal all is to handle like this, useful signal is strengthened, and useless second order inter-modulation signal, third order intermodulation signal obtain good restraining, so good linearity, the power height, the carrier wave that can carry is more.Because the use of superlinearity multicarrier amplifier, thereby play the multiplexing purpose of multicarrier well.Avoid using a plurality of base amplifiers that multi-carrier signal is handled simultaneously, with low cost.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
