20522 carry out phase shift, then carry out amplitude fading by attenuator 20523, can will most adjust after the delay of delayer 2053 afterwards
Interference signal afterwards is transmitted in the receiving channel of 5G signal.
The standard that phase shifter carries out phase shift to the phase of interference signal is: so that interference signal arrives the phase of B point by path 1
Position arrives the phase phase difference 180 degree of B point with interference signal by path 2.In addition, attenuator declines in the amplitude to interference signal
The standard subtracted is: it is identical as the loss in path 2 to need to meet path 1, i.e., must add suitable amplitude attenuation value in path 1,
So that interference signal is equal to the amplitude of B point by path 2 with interference signal by the amplitude in path 1 to B point.Specifically, such as
Shown in Figure 11, two paths from A point to B point are respectively path 1 and path 2, in which: path 1 are as follows: A point-third coupler-
First filter-phase shifter-attenuator-delayer-B point；Path 2 are as follows: A point-third coupler-the-the first radio frequency of duplexer is opened
Close the-the second RF switch of the-the second coupler of the-the first coupler-circulator-B point.
It should be noted that the pad value of above-mentioned attenuator can be transferred in path 1 from A point by emulating 4G signal
The loss of B point and emulation 4G signal are transferred to the loss of B point in path 2 from A point, and combine the signal receiving/transmission device real
Border is to the receiving sensitivity of 5G signal, to determine above-mentioned pad value.It should be noted that under different frequency bands, attenuator
Pad value can carry out appropriate adjustment according to the different of frequency band.
It should be noted that since third coupler generally understands 0~90 degree of phase shift, shifting of the phase shifter to interference signal
Phase degree needs the phase shift degree in conjunction with third coupler to carry out phase shift.
For example, it is assumed that the degree to interference signal phase shift of third coupler is 85 degree, by interference signal from path 1
The phase shift of A point to B point emulate, if 4G signal route via 1 reaches 0.8 degree of phase shift in total in the simulation process of B point, e.g.,
0.5 degree of filter phase shift, 0.2 degree of attenuator phase shift, 0.5 degree of delayer phase shift, be no any shifting in the state of 2 ideal of path
Phase, therefore, phase shifter needs the degree of phase shift are as follows: 180-85-0.8-0.5-0.5-0.2=93 degree.
For example, it is assumed that being 1dB by the energy loss that emulation or test determine that interference signal passes through duplexer, it is assumed that logical
Cross emulation or test determine interference signal by the first RF switch energy loss be 1dB, it is assumed that by emulation or
It tests and determines that energy loss of the interference signal Jing Guo circulator is 25dB, it is assumed that the interference signal is determined by emulation or test
The energy loss that interference signal is transmitted to B point after circulator output is 1dB, then the interference signal is from the A point in path 2 to B point
Gross energy loss be 1dB+1dB+25dB+1dB=28dB, i.e. the interference signal mistake that is coupled to B point by circulator from A point
Energy attenuation 28dB in journey.Assuming that determine that loss is 3.2dB to interference signal in total in path 1 by emulation or test, that
The pad value of attenuator is 28dB-3.2dB=24.8dB.
