In one of the embodiments, as shown in Fig. 2 the first bridge circuitry phase 120 includes the first quadrature bridge 122, second
Quadrature bridge 124, the first wave filter 126 and the second wave filter 128.
Quadrature bridge refers to the electric bridge that output port phase differs 90 degree.The input port of first quadrature bridge 122 is first
The dilatation input port of bridge circuitry phase 120, receives coupling/through connect signal.The coupling port of first quadrature bridge 122 passes through first
Wave filter 126 is connected with the first input port of the second quadrature bridge 124, and the straight-through port of the first quadrature bridge 122 passes through
Two wave filters 128 are connected with the second input port of the second quadrature bridge 124.First quadrature bridge 122 is used for coupling/leading directly to
Signal carries out Phase Processing, obtains and conveying differs 90 degree and phase difference 180 degree with coupling/through connect signal phase respectively
Signal to the first wave filter 126 and the second wave filter 128.
First wave filter 126 and the second wave filter 128 are used to be delivered to respectively after being filtered processing to the signal of reception
The first input port and the second input port of second quadrature bridge 124.
The coupling port of second quadrature bridge 124 is the broadband signal port of the first bridge circuitry phase 120, receives the first wideband
Signal.The straight-through port of second quadrature bridge 124 is the combining output port of the first bridge circuitry phase 120.Second quadrature bridge 124
For carrying out Phase Processing to the signal that the first wave filter 126 and the second wave filter 128 are conveyed respectively, and by the second quadrature bridge
124 straight-through port exports the first mixed signal.
Specifically, the first wave filter 126 is identical with the passband of the second wave filter 128, and with needing the system signal of dilatation
Frequency range is corresponding, to ensure the accuracy of signal extraction.
First quadrature bridge 122 and the second quadrature bridge 124 equally include two ports for accessing signal and two outputs
The port of signal.The port for accessing signal using one of the first quadrature bridge 122 receives coupling/straight-through letter as input port
Number, the port of another access signal can be connected with matched load and (not marked in accompanying drawing).Two of first quadrature bridge 122 are defeated
Go out in the port of signal, the port being joined directly together with input port connects the second wave filter 128, first just as straight-through port
The port of another output signal of alternating current bridge 122 connects the first wave filter 126 as coupling port.Second quadrature bridge 124
The port of two access signals connects the first wave filter 126 and second respectively as first input port and the second input port
In wave filter 128, the port of two output signals of the second quadrature bridge 124, the first input end with the second quadrature bridge 124
The connected port of mouth is used as straight-through port, exports the first mixed signal, the end of another output signal of the second quadrature bridge 124
Mouth is used as coupling port, accesses the first broadband signal.
The concrete operating principle to the first bridge circuitry phase 120 is explained below in conjunction with the accompanying drawings, Fig. 3 and Fig. 4 difference
The phase place change schematic diagram of the first bridge circuitry phase 120 is flowed through for coupling/through connect signal and the first broadband signal.
As shown in figure 3, coupling/through connect signal is by the first quadrature bridge 122, in the output end of the first quadrature bridge 122
It is Ф that mouth, which produces the signal of two 90 degree of phase differences, the i.e. phase of a port signal, then the phase of another port signal is
Ф -90 spends.For the ease of understanding and facilitating calculating, it is assumed that the phase of coupling/through connect signal of input is 0 degree, output port point
Not Shu Chu -90 degree phases signal (coupling port output) and -180 degree phase signal (straight-through port output), two paths of signals
The first wave filter 126 and the second wave filter 128 are passed through respectively, the first wave filter 126 and the second wave filter 128 prevent dilatation frequency
Signal outside section passes through, and the phase of two wave filters is identical, so the signal difference of device is still 90 degree, institute after filtering
With for the ease of calculating, it may be assumed that wave filter is ideal filter, phase is 0 degree.It is orthogonal that the signal of -90 degree phases reaches second
Electric bridge 124, similarly, the signal equally generate the signal of two 90 degree of phase differences in the output port of the second quadrature bridge 124,
The signal (straight-through port output) of the signal (coupling port output) of respectively -180 degree phase and -270 degree phases.And it is another
The signal of individual -180 phase differs 90 degree of signal by equally generating two phases after the second quadrature bridge 124, be respectively -
The signal (straight-through port output) of the signal (coupling port output) of 360 degree of phases and -270 degree phases.Now the second positive alternating current
The coupling port output of bridge 124 is-the 180 degree phase signal equal with the opposite in phase amplitude of -360 degree phases, its amplitude
Same phase is conversely just offset, this port no signal output.The straight-through port of second quadrature bridge 124 exports two -270 degree
The signal of phase, its amplitude same phase is identical, Signal averaging, and power now is equal to the coupling for inputting the first bridge circuitry phase 120
The power of conjunction/through connect signal, the signal of output, which is used to send to antenna-feedback system, to be launched, and completion needs the system signal of dilatation to cover
Lid.
As shown in figure 4, the first broadband signal (can be set to 0 degree of phase) is input to the coupling port of the second quadrature bridge 124,
The signal of two 90 degree of differences is equally generated, a phase is Ф, then another signal phase is spent for Ф -90.For the ease of
Calculate and understand, it is assumed that one be -90 degree phases signals, then another is exactly-the signal of 180 degree phase, this two paths of signals
When being transmitted separately to the first wave filter 126 and the second wave filter 128, because wave filter can not cover signal by original, here
This two paths of signals is totally reflected, and difference upset 180 degree, becomes one -270 signal for spending phase and one -360 is spent phase
Signal (is equal to 0 degree, represented in Fig. 4 with 0 degree), and this two paths of signals is returned to after the second quadrature bridge 124, and generates 2 tunnels respectively
Phase differs 90 degree of signal, and the phase of 0 degree and 180 degree is finally generated in the port (coupling port) of the former covering signal of input
Conversely, amplitude identical signal, cancels out each other.The phase of 2-90 degree is generated on the straight-through port of the second quadrature bridge 124
Identical, the amplitude identical signal in position, is overlapped mutually, and its power is identical with the first broadband signal of input, straight-through port output
Original covering signal is used as being incorporated into antenna-feedback system being covered.
It should be noted that making signal phase overturn 180 when the first wave filter 126 and the second 128 reflected signal of wave filter
Degree is not unique, and according to the difference of actual design, 180 degree is not necessarily herein, such as open circuit design phase bit flipping 0
Degree, short-circuit phase bit flipping is only 180 degree, but designs in any case, and the phase of two wave filter upsets will keep identical, makes anti-
Upset difference when penetrating is 0 degree, i.e., do not change the phase difference value of original signal.
