Above-mentioned POI flash chamber, dilatation electric bridge 110 receives the signal that capacity-enlarging system is carried, and exports respectively coupling/through connect signal and straight-through/coupled signal to the first bridge circuitry phase 120 and the second bridge circuitry phase 130.The first bridge circuitry phase 120 receives the first broadband signal and coupling/through connect signal and exports the first mixed signal; The second bridge circuitry phase 130 receives the second broadband signal and straight-through/coupled signal and exports the second mixed signal.By the first bridge circuitry phase 120 and the second bridge circuitry phase 130 to needing the signal of dilatation to carry out obtaining after filtering, Phase Processing the signal of required dilatation frequency range, and the signal that accesses the dilatation after former covering signal processing is together exported, as covering through antenna-feedback system transmitting, realize System Expansion, due to without the structure of existing POI equipment is improved, and complicated technical barrier is simplified and just can be realized dilatation, simple in structure, easy to operate and cost is low.
In an embodiment, as shown in Figure 2, the first bridge circuitry phase 120 comprises the first quadrature bridge 122, the second quadrature bridge 124, the first filter 126 and the second filter 128 therein.
Quadrature bridge refers to the electric bridge that output port phase phasic difference 90 is spent.The input port of the first quadrature bridge 122 is the dilatation input port of the first bridge circuitry phase 120, receives coupling/through connect signal.The coupling port of the first quadrature bridge 122 is connected with the first input end mouth of the second quadrature bridge 124 by the first filter 126, and the straight-through port of the first quadrature bridge 122 is connected with the second input port of the second quadrature bridge 124 by the second filter 128.The coupling port of the second quadrature bridge 124 is the broadband signal port of the first bridge circuitry phase 120, receives the first broadband signal.The straight-through port of the second quadrature bridge 124 is the first bridge circuitry phase 120He road output port, output the first mixed signal.Particularly, the first filter 126 is identical with the passband of the second filter 128, and with need the system signal frequency range of dilatation corresponding, to guarantee the accuracy of signal extraction.
The first quadrature bridge 122 and the second quadrature bridge 124 comprise two access ports of signal and the port of two output signals equally.Using the port of an access signal of the first quadrature bridge 122 as input port, receive coupling/through connect signal, the port of another access signal can be connected with matched load (in accompanying drawing, not marking).In the port of two output signals of the first quadrature bridge 122, the port being directly connected with input port is as straight-through port, connect the port of another output signal of the second filter 128, the first quadrature bridges 122 as coupling port, connect the first filter 126.The port of two access signals of the second quadrature bridge 124 is as first input end mouth and the second input port, connect respectively the first filter 126 and the second filter 128, in the port of two output signals of the second quadrature bridge 124, the port being connected with the first input end mouth of the second quadrature bridge 124 is as straight-through port, export the first mixed signal, the port of another output signal of the second quadrature bridge 124, as coupling port, accesses the first broadband signal.
Below in conjunction with accompanying drawing, the specific works principle of the first bridge circuitry phase 120 is explained, Fig. 3 and Fig. 4 are respectively the flow through phase place of the first bridge circuitry phase 120 of coupling/through connect signal and the first broadband signal and change schematic diagram.
As shown in Figure 3, coupling/through connect signal, by the first quadrature bridge 122, produces the signal of two 90 degree phase differences at the output port of the first quadrature bridge 122, and the phase place of a port signal is Ф, and the phase place of another port signal is Ф-90 degree.For the ease of understanding and convenient calculating, the phase place of supposing the coupling/through connect signal of input is 0 degree, output port is exported respectively the signal (coupling port output) of-90 degree phase places and the signal (straight-through port output) of-180 degree phase places, two paths of signals has passed through respectively the first filter 126 and the second filter 128, the first filter 126 and the second filter 128 stop the signal outside dilatation frequency range to pass through, and the phase place of two filters is identical, so to differ be still 90 degree to the signal of device after filtering, so for the ease of calculating, can suppose that filter is ideal filter, phase place is 0 degree.The signal of-90 degree phase places arrives the second quadrature bridge 124, in like manner, this signal has produced the signal of two 90 degree phase differences equally at the output port of the second quadrature bridge 124, be respectively the signal (coupling port output) of-180 degree phase places and the signal (straight-through port output) of-270 degree phase places.And the signal of another-180 phase places is by rear same two signals that phase phasic difference 90 is spent that produced of the second quadrature bridge 124, be respectively the signal (coupling port output) of-360 degree phase places and the signal (straight-through port output) of-270 degree phase places.What now the coupling port of the second quadrature bridge 124 was exported is the equal signals of single spin-echo amplitude of-180 degree phase places and-360 degree phase places, and its amplitude same phase is just offset on the contrary, and this port no signal is exported.The signal of two-270 degree phase places of straight-through port output of the second quadrature bridge 124, its amplitude same phase is identical, signal stack, power now equals the power of coupling/through connect signal of inputting the first bridge circuitry phase 120, the signal of output is used for being sent to antenna-feedback system to be launched, and completes and needs the system signal of dilatation to cover.
As shown in Figure 4, the first broadband signal (can be made as 0 degree phase place) is input to the coupling port of the second quadrature bridge 124, has produced equally two signals that differ 90 degree, and a phase place is Ф, and another signal phase is Ф-90 degree.For the ease of calculating and understanding, suppose that one is the signal of-90 degree phase places, another is exactly the signal of-180 degree phase places, when this two paths of signals transfers to respectively the first filter 126 and the second filter 128, because filter can not be by former covering signal, this two paths of signals is totally reflected herein, differ and turn over turnback, the signal and one-360 signal of spending phase place that have become one-270 degree phase place (equal 0 degree, in Fig. 4, represent with 0 degree), this two paths of signals is got back to after the second quadrature bridge 124, produce respectively again the signal that 2 tunnel phase phasic differences 90 are spent, finally produced the single spin-echo of 0 degree and 180 degree at the port (coupling port) of the former covering signal of input, the signal that amplitude is identical, cancel out each other.On the straight-through port of the second quadrature bridge 124, produce the signal that phase place is identical, amplitude is identical of 2-90 degree, stack mutually, the first broadband signal of its power and input is identical, and the former covering signal of straight-through port output covers as being incorporated in antenna-feedback system.
It should be noted that, it is not unique when the first filter 126 and the second filter 128 reflected signal, making signal phase turn over turnback, according to the difference of actual design, 180 degree not necessarily herein, such as when design open circuit phase overturn 0 spend, when short circuit, phase overturn is only 180 degree, but design in any case, the phase place of two filters upset will keep identical, and it is 0 degree that the upset of reflex time is differed, and does not change the phase difference value of original signal.
In an embodiment, continue with reference to Fig. 2 therein, the second bridge circuitry phase 130 comprises the 3rd quadrature bridge 132, the 4th quadrature bridge 134, the 3rd filter 136 and the 4th filter 138.
