Because the first transmitting-receiving interface 1 may further include at least two first transmitting-receiving ports 11, and each first transmitting-receiving port 11 is corresponding with at least one pair of transmission channel and receive path among the transceiver A; The second transmitting-receiving interface 2 may further include at least two second transmitting-receiving ports 21, and each second transmitting-receiving port 21 is corresponding with an antenna among the antenna sets C with one first transmitting-receiving port 11 respectively.Therefore, under the enforcement scene of present embodiment, a coupler 34 can corresponding one first transmitting-receiving port 11 and one second transmitting-receiving port 21.For example: first radiofrequency signal that coupler 34a shown in Figure 2 can receive the first transmitting-receiving port 11a of correspondence is coupled to the second corresponding transmitting-receiving port 21a; So that first radiofrequency signal is sent to corresponding antenna C1 through the second transmitting-receiving port 21a; And first radiofrequency signal that coupler 34a can receive the second transmitting-receiving port 21a of correspondence is coupled to mixing device 32.Further; Each coupler 34 can also be coupled respectively to the two paths of signals at least that first power divider 33 obtains by power division the first corresponding transmitting-receiving port 11 of two-way receive path at least from second radiofrequency signal; For example: coupler 34a shown in Figure 2 can be coupled to the road signal that first power divider 33 obtains by power division the first corresponding transmitting-receiving port 11a from second radiofrequency signal; So that the first transmitting-receiving port 11a sends to corresponding receive path 1 with this road signal; Same; Coupler 34b can be coupled to the road signal that first power divider 33 obtains by power division the first corresponding transmitting-receiving port 11b from second radiofrequency signal; So that the first transmitting-receiving port 11b sends to corresponding receive path 2 with this road signal, thereby realize that two paths of signals sends to two-way receive path at least from the first transmitting-receiving port 11 that the two-way receive path is corresponding at least respectively at least.
Still comprise 2 pairs of transmission channels and receive path among the transceiver A with aforementioned hypothesis: transmission channel 1 and receive path 1, and transmission channel 2 and receive path 2; Antenna sets C comprises 2 antennas: antenna C1 and antenna C2 are that example describes.The first transmitting-receiving interface 1 shown in Figure 2 comprises two first transmitting-receiving ports 11, is respectively the first transmitting-receiving port 11a and the first transmitting-receiving port 11b; Comprising two second transmitting-receiving ports 21 in the second transmitting-receiving interface 2, is respectively the second transmitting-receiving port 21a and the second transmitting-receiving port 21b; Comprising two couplers 34 in the radio frequency unit 3, is respectively coupler 34a and coupler 34b.Wherein, transmission channel 1 and receive path 1 are corresponding with the first transmitting-receiving port 11a, the second transmitting-receiving port 21a, antenna C1 and coupler 34a respectively; Transmission channel 2 and receive path 2 are corresponding with the first transmitting-receiving port 11b, the second transmitting-receiving port 21b, antenna C2 and coupler 34b respectively.
Transmission channel 1 among the transceiver A sends first radiofrequency signal; This first radiofrequency signal through one of amplifier, the external filter in base station, combiner-divider etc. or any several function device (device) on the tower that possibly be provided with between feeder line B, feeder line B and the time delay adjustment equipment after; Received by the first transmitting-receiving port 11a; Coupler 34a is coupled to the second transmitting-receiving port 21a with this first radiofrequency signal; Make this first radiofrequency signal send to antenna C1, because each antenna can receive the radiofrequency signal of other antenna transmission through electromagnetic wave among the antenna sets C, therefore through the second transmitting-receiving port 21a; Antenna C2 can receive first radiofrequency signal that antenna C1 sends through electromagnetic wave; Antenna C2 returns to the second transmitting-receiving port 21b with this first radiofrequency signal, and coupler 34b is coupled to mixing device 32 with first radiofrequency signal that this second transmitting-receiving port 21b returns, and mixing device 32 carries out mixing with the local oscillator radiofrequency signal of this first radiofrequency signal and 31 generations of local frequency oscillator; Obtain second radiofrequency signal (receive frequency of duplexer is complementary among the frequency of this second radiofrequency signal and the transceiver A); And this second radiofrequency signal is sent in first power divider 33,33 pairs second radiofrequency signals of first power divider become two paths of signals according to the power division of setting, and wherein one road signal sends to coupler 34a; Coupler 34a will be from being coupled to this road signal the first transmitting-receiving port 11a, so that this road signal is sent to corresponding receive path 1 through the first transmitting-receiving port 11a; Equally, from second radiofrequency signal, distribute another road signal that obtains to send to coupler 34b, coupler 34b is coupled to the first transmitting-receiving port 11b with this road signal, so that this road signal is sent to corresponding receive path 2 through the first transmitting-receiving port 11b.
After receive path 1 receives second radiofrequency signal respectively with receive path 2; Transceiver A can be a benchmark with the transmitting time of transmission channel 1 emission first radiofrequency signal; According to the time of receive path 1, the time delay between receive path 1 and the receive path 2 is proofreaied and correct with receive path 2 receptions second radiofrequency signal.Wherein, second radiofrequency signal that receives of receive path 1 and receive path 2 is in fact respectively that 33 pairs second radiofrequency signals of first power divider are carried out the two paths of signals that obtains after the power division in the time delay adjustment equipment.
The transmitting time that is merely first radiofrequency signal of sending with transmission channel 1 shown in Figure 2 is a benchmark; Time delay between receive path 1 and the receive path 2 is proofreaied and correct; It is understandable that; The transmitting time of first radiofrequency signal that can also send with transmission channel 2 is a benchmark, and the time delay between receive path 1 and the receive path 2 is proofreaied and correct.
Because certain port in the second transmitting-receiving interface 2; For example: the second transmitting-receiving port 21a is after corresponding antenna C1 sends first radiofrequency signal; This first radiofrequency signal also has part and turns back to this second transmitting-receiving port 21a; And through in the coupler 34a entering frequency mixer 32, thereby first radiofrequency signal that the antenna C2 that receives at 32 pairs second transmitting-receivings of frequency mixer port 21b returns is brought interference signal when carrying out mixing, in view of the above; Implement under the scene at the another kind of present embodiment; Can further be provided with between second power divider, 35, the second power dividers 35 and each coupler 34 between any two couplers 34 and can be provided with first switching device 36, each first switching device can be corresponding with matched load 37; Second power divider 35 can be connected with mixing device 32;
Wherein, When any coupler in two couplers 34 is connected with second power divider 35 through first switching device 36; Another coupler connects with corresponding matched load 37 through first switching device 36; So that first radiofrequency signal that coupler 34 corresponding antenna are returned in two couplers 34 arrives mixing devices 32 through second power divider 35, first radiofrequency signal that another coupler 34 corresponding antenna are returned is absorbed by matched load 37.
Still be example, be provided with between coupler 34a and the coupler 34b between second power divider, 35, the second power dividers 35 and the coupler 34a and be provided with the first switching device 36a that this first switching device 36a is also corresponding with a matched load 37a with Fig. 2; Equally, be provided with the first switching device 36b between second power divider 35 and the coupler 34b, this first switching device 36b is also corresponding with a matched load 37b.In addition, second power divider 35 also is connected with mixing device 32.
When the transmitting time with first radiofrequency signal of transmission channel 1 emission is a benchmark; Proofread and correct the time time-delay between receive path 1 and the receive path 2; Can the first switching device 36a be connected with matched load 37a; This matched load 37a is used to absorb first radiofrequency signal that antenna C1 returns, and prevents that this first radiofrequency signal from getting into mixing device 32 through second power divider 35; The first switching device 36b is connected with second power divider 35, thereby first radiofrequency signal that makes antenna C2 return to the second transmitting-receiving port 21b gets into mixing device 32 through second power divider 35.
When the transmitting time with first radiofrequency signal of transmission channel 2 emission is a benchmark; Proofread and correct the time time-delay between receive path 1 and the receive path 2; Can the first switching device 36a and second power divider 35 be connected; The first switching device 36b and matched load 37b connect, thereby antenna C1 arrives mixing device 32 from first radiofrequency signal that the second transmitting-receiving port 21a returns through second power divider 35.
Implement between second power divider 35 and the mixing device 32 second switch device 38 can also be set further in the scene at one, this second switch device 38 is also corresponding with a mismatch load 39;
Be connected with second power divider 35 when mixing device 32 passes through second switch device 38, then second power divider 35 is sent to mixing device 32 with first radiofrequency signal; When mixing device 32 is connected through second switch device 38 and mismatch load 39, then mismatch load 39 second radiofrequency signal that can be used to 32 mixing of mixing device are obtained gets into first power divider 33.
For example: coupler 34a shown in Figure 2 is connected with second power divider 35 through the first switching device 36a; Mixing device 32 can at first be connected with second power divider 35 through second switch device 38, to receive first radiofrequency signal from coupler 34a.Treat that 32 pairs of these first radiofrequency signals of mixing device carry out mixing and obtain after second radiofrequency signal; Mixing device 32 can be connected with mismatch load 39 through second switch device 38; Because the effect of reflected signal is played in mismatch load 39; Therefore, mismatch load 39 can fully get into first power divider with second radiofrequency signal that 32 mixing of mixing device obtain.
In the description of front to be provided with 2 pairs of transmission channels and receive path among the transceiver A; Comprise two antennas among the antenna sets C; In the time delay adjustment equipment first transmitting-receiving interface 1 comprises two first transmitting-receiving ports 11; The second transmitting-receiving interface 2 comprises that two second transmitting-receiving ports 21 are example, and a kind of feasible configurations of time delay adjustment equipment is specified.Yet, not with this restriction as the time delay adjustment equipment that the embodiment of the invention is provided.Implement under the scene at the another kind that present embodiment provides; The first transmitting-receiving port 11 can be corresponding with the transmission channel and the receive path of 2 couple among the transceiver A or corresponding setting more than 2 pairs; For example: suppose to have 4 pairs of transmission channels and receive path among the transceiver A; The first transmitting-receiving port 11a shown in Figure 2 can with the transmission channel 1 and receive path 1 in 4 pairs of transmission channels and the receive path, and transmission channel 2 and receive path 2 correspondences, promptly; The first transmitting-receiving port 11a both can be used as transmission channel 1 and the interface unit of receive path 1 with time delay adjustment equipment, also can be used as transmission channel 2 and the interface unit of receive path 2 with time delay adjustment equipment.
Under this enforcement scene, the second transmitting-receiving port 21 is still corresponding with one first transmitting-receiving port 11 and an antenna, and a coupler 34 also still can one first of correspondence be received and dispatched port 11 and one second transmitting-receiving port 21, specifically can be referring to the description of front.
Because in the prior art; When having more than 2 pairs transmission channel and receive path among the transceiver A; Usually also can adopt many antennas, therefore, under this enforcement scene; The time delay adjustment equipment that the embodiment of the invention provides also can increase the number of the first transmitting-receiving port 11, the second transmitting-receiving port 21 and coupler 34 accordingly, makes the radical of number and antenna of the first transmitting-receiving port 11, the second transmitting-receiving port 21 and coupler 34 consistent.
Can find out from the description of front; First switching device 36, second power divider 35, matched load 37; And second switch device 38 is for to be arranged on two additional devices between the coupler 34, and therefore, these devices are also along with the increase and the corresponding increase of coupler 34 numbers.And the number of local frequency oscillator 31, mixing device 32 and first power divider can only be provided with one, also can also suitably increase along with the number increase of coupler 34.
Implement under the scene for one at present embodiment; Suppose that transceiver A has 3 pairs of transmission channels and receive path; Have 3 antennas among the antenna sets C; Then have in first of the time delay adjustment equipment transmitting-receiving interface 1 in 3 first transmitting-receiving ports, 11, the second transmitting-receiving interfaces 2 and have 3 second transmitting-receiving ports 21, and time delay adjustment equipment has 3 couplers 34.After the first transmitting-receiving port 11a receives first radiofrequency signal of transmission channel 1 transmission; Coupler 34a is coupled to the second transmitting-receiving port 21a with this first radiofrequency signal; So that this first radiofrequency signal sends to antenna C1 through the second transmitting-receiving port 21a; Because antenna C2 and antenna C3 all can receive first radiofrequency signal through electromagnetic transmission, in this case, owing to first radiofrequency signal that an antenna is returned is carried out mixing and is obtained second radiofrequency signal; Just can realize that at least two receive paths in 3 receive paths return respectively through second radiofrequency signal after the power division; Therefore, under this enforcement scene, can antenna C2 or the corresponding coupler 34 of antenna C3 be turn-offed; So that the corresponding coupler 34 of antenna C2 or antenna C3 no longer works, and then first radiofrequency signal that antenna C2 or antenna C3 are returned is no longer carried out Frequency mixing processing.
More than the time delay adjustment equipment that provides of each embodiment; The radiofrequency signal that arbitrary transmission channel in the transceiver is sent is successively through one or any several function elements such as amplifier, the external filter in base station, combiner-divider on the tower that possibly be provided with between feeder line, feeder line and the time delay adjustment equipment; And antenna sets is carried out mixing afterwards; The signal that obtains is returned to the receive path of two-way at least in the transceiver; Thereby making transceiver can be benchmark with the signal sending time of transmission channel, obtains the time delay between the two-way receive path at least.
It is understandable that; As another kind of possible implementation; Time delay adjustment equipment can also with in the transceiver at least the radiofrequency signal sent of two-way transmission channel successively through one of amplifier, the external filter in base station, combiner-divider etc. on the tower that possibly be provided with between feeder line, feeder line and the time delay adjustment equipment or carry out mixing after several other function elements and the antenna sets arbitrarily; The two paths of signals at least that obtains is returned to the arbitrary road receive path in the transceiver; Thereby making the time of reception of the road signal that transceiver can receive with receive path is benchmark, obtains the time delay between the two-way transmission channel at least.In view of the above, the present invention also provides time delay adjustment equipment another embodiment, and its structure can be referring to shown in Figure 1, and this time delay adjustment equipment comprises: the first transmitting-receiving interface 1, second is received and dispatched interface 2 and radio frequency unit 3; Wherein:

Need to prove; Implement in the scene for one in the embodiment of the invention; At least one pair of transmission channel among each first transmitting-receiving port 11 and transceiver A and receive path is corresponding is meant; For example: suppose to be provided with 2 pairs of transmission channels and receive path among the transceiver A shown in Figure 1, be respectively: transmission channel 1 and receive path 1, transmission channel 2 and receive path 2.Then also be example with shown in Figure 2, the first transmitting-receiving port 11a can be corresponding with transmission channel 1 and receive path 1, as transmission channel 1 and the interface unit of receive path 1 with time delay adjustment equipment; The first transmitting-receiving port 11b can be corresponding with transmission channel 2 and receive path 2, as transmission channel 2 and the interface unit of receive path 2 with time delay adjustment equipment.
Each second transmitting-receiving port 21 respectively with one first transmitting-receiving port 11 and antenna sets C in corresponding being meant of antenna; For example: suppose to comprise among the antenna sets C shown in Figure 1 two antennas; Be respectively antenna C1 and antenna C2; Then also can be corresponding with the first transmitting-receiving port 11a and antenna C1 respectively with the second transmitting-receiving port 21a shown in Figure 2; After the first transmitting-receiving port 11a received the 3rd radio frequency signal, radio frequency unit 3 can be coupled to the second transmitting-receiving port 21a with the 3rd radio frequency signal, made the second transmitting-receiving port 21a that the 3rd radio frequency signal is sent to antenna C1; Same; The second transmitting-receiving port 21b shown in Figure 2 can be corresponding with the first transmitting-receiving port 11b and antenna C2 respectively; After the first transmitting-receiving port 11b receives the 3rd radio frequency signal; Radio frequency unit 3 can be coupled to the second transmitting-receiving port 21b with the 3rd radio frequency signal, makes the second transmitting-receiving port 21b that the 3rd radio frequency signal is sent to antenna C2.Because the first transmitting-receiving interface 1 may further include at least two first transmitting-receiving ports 11, and each first transmitting-receiving port 11 is corresponding with at least one pair of transmission channel and receive path among the transceiver A; The second transmitting-receiving interface 2 may further include at least two second transmitting-receiving ports 21, and each second transmitting-receiving port 21 is corresponding with an antenna among the antenna sets C with one first transmitting-receiving port 11 respectively.Therefore, under the enforcement scene of present embodiment, a coupler 34 can corresponding one first transmitting-receiving port 11 and one second transmitting-receiving port 21.For example: the 3rd radio frequency signal that coupler 34a shown in Figure 2 can receive the first transmitting-receiving port 11a of correspondence is coupled to the second corresponding transmitting-receiving port 21a; So that the 3rd radio frequency signal is sent to corresponding antenna through the second transmitting-receiving port 21a; And the 3rd radio frequency signal that coupler 34a can receive the second transmitting-receiving port 21a of correspondence is coupled to mixing device 32.Further, coupler 34 can also be coupled to the 4th radiofrequency signal that mixing device 32 obtains the first corresponding transmitting-receiving port 11 of arbitrary receive path, so that the 4th radiofrequency signal sends to receive path from the first corresponding transmitting-receiving port 11 of receive path.For example: coupler 34a shown in Figure 2 can be coupled to the 4th radiofrequency signal that mixing device 32 obtains the first corresponding transmitting-receiving port 11a, so that the first transmitting-receiving port 11a sends to corresponding receive path 1 with the 4th radiofrequency signal.
Because present embodiment is that the 4th radiofrequency signal that every road the 3rd radio frequency signal mixing obtains is all sent to same road receive path, therefore, can not need first power divider 33 in the present embodiment.
Still to comprise 2 pairs of transmission channels and receive path among the transceiver A: transmission channel 1 and receive path 1, and transmission channel 2 and receive path 2; Antenna sets C comprises 2 antennas: antenna C1 and antenna C2 are that example describes.The first transmitting-receiving interface 1 shown in Figure 2 comprises two first transmitting-receiving ports 11, is respectively the first transmitting-receiving port 11a and the first transmitting-receiving port 11b; Comprising two second transmitting-receiving ports 21 in the second transmitting-receiving interface 2, is respectively the second transmitting-receiving port 21a and the second transmitting-receiving port 21b; Comprising two couplers 34 in the radio frequency unit 3, is respectively coupler 34a and coupler 34b.Wherein, transmission channel 1 and receive path 1 are corresponding with the first transmitting-receiving port 11a, the second transmitting-receiving port 21a, antenna C1 and coupler 34a respectively; Transmission channel 2 and receive path 2 are corresponding with the first transmitting-receiving port 11b, the second transmitting-receiving port 21b, antenna C2 and coupler 34b respectively.
Transmission channel 1 among the transceiver A send the 3rd radio frequency signal through one of amplifier, the external filter in base station, combiner-divider etc. or any several function device (device) on the tower that possibly be provided with between feeder line B, feeder line B and the time delay adjustment equipment after; Received by the first transmitting-receiving port 11a; Coupler 34a is coupled to the second transmitting-receiving port 21a with the 3rd radio frequency signal; So that the 3rd radio frequency signal sends to antenna C1 through the second transmitting-receiving port 21a; Antenna C2 can receive the 3rd radio frequency signal that antenna C1 sends through electromagnetic wave; Antenna C2 returns to the second transmitting-receiving port 21b with the 3rd radio frequency signal; Coupler 34b is coupled to mixing device 32 with the 3rd radio frequency signal that this second transmitting-receiving port 21b returns, and mixing device 32 carries out mixing with the local oscillator radiofrequency signal of the 3rd radio frequency signal and 31 generations of local frequency oscillator, obtains the 4th radiofrequency signal (receive frequency of duplexer is complementary among the frequency of the 4th radiofrequency signal and the transceiver A); Coupler 34a is coupled to the first transmitting-receiving port 11a with the 4th radiofrequency signal, so that the 4th radiofrequency signal is sent to corresponding receive path 1 through the first transmitting-receiving port 11a.Similarly; After the 3rd radio frequency signal that transmission channel 2 sends is received by the first transmitting-receiving port 11b; Be coupled device 34b and be coupled to the second transmitting-receiving port 21b; And send to antenna C2 through the second transmitting-receiving port 21b, and antenna C1 returns to the second transmitting-receiving port 21a with this radiofrequency signal after receiving the 3rd radio frequency signal, and coupler 34a is sent to the 3rd radio frequency signal after mixing device 32 carries out mixing; The 4th radiofrequency signal that coupler 34a will obtain is coupled to the first transmitting-receiving port 11a, so that the 4th radiofrequency signal is sent to corresponding receive path 1 through the first transmitting-receiving port 11a.
Situation about being connected with coupler 34a for the output of mixing device 32 shown in Figure 2; Be that every road the 4th radiofrequency signal that mixing device 32 will obtain all sends to coupler 34a; So that coupler 34a is coupled every road the 4th radiofrequency signal to the first transmitting-receiving port 11a; So that every road the 4th radiofrequency signal all sends to receive path 1 through the first transmitting-receiving port 11a; Thereby realization transceiver A is a benchmark with the time of reception of arbitrary road the 4th radiofrequency signal that receive path 1 receives, the time delay between correct transmission passage 1 and the transmission channel 2; As the feasible embodiment of another kind; The output of mixing device 32 can also be connected with coupler 34b; Under this enforcement scene, coupler 34b can be coupled every road the 4th radiofrequency signal to the first transmitting-receiving port 11b, so that every road the 4th radiofrequency signal all sends to receive path 2 through the first transmitting-receiving port 11b; Thereby realization is a benchmark with the time of reception of arbitrary road the 4th radiofrequency signal that receive path 2 receives, the time delay between correct transmission passage 1 and the transmission channel 2.
After receive path 1 receives the 4th radiofrequency signal of the 4th corresponding radiofrequency signal of the 3rd radio frequency signal of transmission channel 1 emission and the 3rd radio frequency signal correspondence of transmission channel 2 emissions respectively; Transceiver A can obtain the time delay between transmission channel 1 and the receive path 1 respectively; And the time delay between transmission channel 2 and the receive path 1; Can also obtain the time delay between two-way the 4th radiofrequency signal that receive path 1 receives; The time of reception of arbitrary road the 4th radiofrequency signal that transceiver A can receive with receive path 1 is a benchmark; Obtain the time delay between transmission channel 1 and the transmission channel 2, and then can carry out delay correction to transmission channel 1 and transmission channel 2 based on the time delay that obtains.
Because certain port in the second transmitting-receiving interface 2; For example: the second transmitting-receiving port 21a is after respective antenna C1 sends the 3rd radio frequency signal; The 3rd radio frequency signal also has part and turns back to this second transmitting-receiving port 21a, and gets in the mixing device 32 through coupler 34a, thereby the 3rd radio frequency signal that the antenna C2 that receives at 32 pairs second transmitting-receivings of frequency mixer port 21b returns brings interference signal when carrying out mixing; In view of the above; Another kind at present embodiment is implemented under the scene, if the transmission channel of two-way at least among the transceiver A adopts time division multiplexing mode to send the 3rd radio frequency signal, between then any two couplers 34 second power divider 35 can be set further; Can be provided with first switching device 36 between second power divider 35 and each coupler 34, each first switching device can be corresponding with matched load 37; Second power divider 35 can be connected with mixing device 32;
Wherein, When any coupler in two couplers 34 is connected with second power divider 35 through first switching device 36; Another coupler connects with corresponding matched load 37 through first switching device 36; So that the 3rd radio frequency signal that coupler 34 corresponding antenna are returned in two couplers 34 arrives mixing devices 32 through second power divider 35, the 3rd radio frequency signal that another coupler 34 corresponding antenna are returned is absorbed by matched load 37.

When transmission channel 1 when time delay adjustment equipment sends the 3rd radio frequency signal; Can the first switching device 36a be connected with matched load 37a; This matched load 37a is used to absorb the 3rd radio frequency signal that antenna C1 returns, and prevents that the 3rd radio frequency signal from getting into mixing device 32 through second power divider 35; The first switching device 36b is connected with second power divider 35, thereby the 3rd radio frequency signal that makes antenna C2 return to the second transmitting-receiving port 21b gets into mixing device 32 through second power divider 35.
When transmission channel 2 when time delay adjustment equipment sends the 3rd radio frequency signal; Can the first switching device 36a and second power divider 35 be connected; The first switching device 36b and matched load 37b connect, thereby antenna C1 arrives mixing device 32 from the 3rd radio frequency signal that the second transmitting-receiving port 21a returns through second power divider 35.
In another enforcement scene of present embodiment, between second power divider 35 and the mixing device 32 second switch device 38 can be set further, this second switch device 38 is also corresponding with a mismatch load 39;
Be connected with second power divider 35 when mixing device 32 passes through second switch device 38, then second power divider 35 is sent to mixing device 32 with the 3rd radio frequency signal; When mixing device 32 is connected through second switch device 38 and mismatch load 39, then mismatch load 39 the 4th radiofrequency signal that can be used to 32 mixing of mixing device are obtained gets into coupler 34.
For example: coupler 34a shown in Figure 2 is connected with second power divider 35 through the first switching device 36a; Mixing device 32 can at first be connected with second power divider 35 through second switch device 38, to receive the 3rd radio frequency signal from coupler 34a.Treat that 32 pairs the 3rd radio frequency signals of mixing device carry out mixing and obtain after the 4th radiofrequency signal; Mixing device 32 can be connected through second switch device 38 and mismatch load 39; Because the effect of reflected signal is played in mismatch load 39; Therefore, mismatch load 39 can fully get into coupler 34a with the 4th radiofrequency signal that 32 mixing of mixing device obtain.
