Fig. 5 is the telecommunication circuit of Photocatalyst air purification device provided by the invention, as shown in figure 5, provided by the invention
Telecommunication circuit（Communication unit）At least telecommunication circuit includes at least road circulator 702 and bucking circuit, and the bucking circuit includes
First power splitter 701, the first modulation circuit 703, the second modulation circuit 704, third modulation circuit 705, combiner 706, second
Power splitter 707 and amplitude-phase detection circuit 708, wherein the carrier signal that the first effector 701 is used to input carries out power
It is respectively supplied to the first modulation circuit 703, the second modulation circuit 704, third modulation circuit 705 and circulator 702；Second
The signal that effector 707 is used to provide circulator 702 carries out power distribution, and the combiner 706 and amplitude provided respectively is believed
Detection unit 708；Amplitude believe detection unit 708 for detect in input signal isolation due to circulator 702 it is insufficient and
The first amplitude and first phase for the carrier wave directly revealed, due to the second amplitude and second for the carrier wave that antenna mismatches and reveals
Phase, the third amplitude and third phase of the carrier wave revealed due to Ambient, and it is supplied to processor 130, the processing
The information generation that device 130 is provided according to amplitude-phase detection unit controls the first modulation circuit 703, the second modulation circuit respectively
The control signal of 704 third modulation circuit 705, the first modulation circuit 703, the second modulation circuit 704, third modulation circuit
705 respectively according to respective control signal to carrier signal into line amplitude adjust and phase adjustment to be carried with the second power splitter 707
The signal of confession is added in combiner 706, the carrier wave directly revealed to offset the isolation deficiency of circulator；Due to
Antenna is mismatched and the carrier wave revealed and the carrier wave revealed due to Ambient.Preferably, three modulation circuits wrap
Include phase shifter and adjustable attenuator, respectively according to processor provide control signal to carrier signal into line amplitude adjust and phase
Adjustment provides signal from combiner to the receives link of communication unit.
Receives link is that the reflection that leakage carrier wave, the antenna of circulator mismatch caused reflection carrier wave, environment generates carries
The vector signal of the wanted carrier mixing of wave, corresponding offset reveals carrier wave to three road modulation circuits all the way respectively, but amplitude-phase
The amplitude and phase difference that detection unit detects the carrier wave and leakage carrier wave of the different modulation circuit output in three tunnels simultaneously are highly difficult
, but since the variation of the carrier phase for the leakage that the isolation of circulator is inadequate and generates is substantially stationary, amplitude
Substantially it can be determined according to circulator and carrier wave transmission power, and since the reflection carrier wave that antenna mismatches and generates can also be big
It causes to determine its amplitude and phase change, what is most possibly changed is the reflection carrier wave that environment generates, and closed loop feedback is needed constantly to adjust
Section, until find one more accurately modulation value offset the road-load wave.
Since there are measurement error or other reasons, doing one-shot measurement can not be completely counterbalanced by, therefore the conjunction after counteracting
Device 706 output end in road has accessed a power detector, and the power detector is connect with processor, at detection signal feeding
Device 130 is managed, processor 130 judges offset result according to the signal, until the value that power detector detects reaches requirement.
Telecommunication circuit provided by the invention is offset by three-channel carrier than more thoroughly as a result of carrier cancellation circuit
The carrier wave leakage for solving the problems, such as telecommunication circuit, and by closed loop adjusting better carrier wave inhibition can be obtained.In the present invention
