Frequency have overlapping.Further include the 3rd duplexer 23, transmission terminal 231, receiving terminal 232 and the antenna end of the 3rd duplexer 23
Son 233 in power amplifier 10 respectively with sending in the 3rd upstream Interface of uplink signal of the 3rd frequency range, wireless transceiver 40
The 3rd downstream interface for receiving the downlink signal of the 3rd frequency range is connected with antenna；The frequency of the downlink signal of 3rd frequency range with it is secondary
The frequency of harmonic wave is not overlapped；
In the present embodiment, the function at harmonic wave consumption end is realized by the 3rd duplexer 23.
The moved end of single-pole double-throw switch (SPDT) 61 is connected with the first upstream Interface；First non-moving end of single-pole double-throw switch (SPDT) 61 and the

During the wireless receiving and dispatching realized in carrier aggregation, as shown in figure 4, controlling multiple frequency ranges by wireless transceiver 40
The transmitting-receiving of signal, the signal of multiple frequency ranges are first amplified by power amplifier 10 and then are sent to wireless switching 50 by duplexer,
Wireless switching 50 selects the corresponding passage of the frequency range to be sent out wireless signal, in the present solution, company because of duplexer and antenna
Known in connecing, the connection mode between duplexer, wireless switching 50 and antenna is not elaborated.Duplexer is for example shown in Fig. 4
First duplexer 21, the second duplexer 22 and the 3rd duplexer 23, be used to implement wireless signal and send (such as B4TX, B3TX

Such as the second harmonic of B8 have with the frequency of the downlink signal of B3 it is overlapping, then the second harmonic of B8 can influence B3 signal receive
Quality.
In scheme shown in Fig. 4, if the frequency range combination and operating mode of carrier aggregation can cause harmonic wave interference,
Then pass through the moved end (terminal in left side) of single-pole double-throw switch (SPDT) 61, the first non-moving end (terminal of lower right-hand side) and the second non-moving end
(terminal above right side) into the adjustment of row of channels, so as to avoid the appearance of harmonic wave interference.Detailed process is described as follows：If the
One frequency range (B3) is used as secondary cell frequency range, and the second frequency range (B8) is used as main plot frequency range, and the second frequency range sends signal and generates at this time
Second harmonic interference can be generated to the downlink signal of the first frequency range, it is necessary to second harmonic is isolated, i.e., by moved end and the
Two non-moving ends turn on, and second harmonic can only guide the access of the 3rd frequency range (B4) by single-pole double-throw switch (SPDT) 61, because secondary humorous
Ripple does not have that frequency is overlapping with the downlink signal of the 3rd frequency range, it will not be interfered.If the first frequency range is as main plot frequency
Section, for the second frequency range as secondary cell frequency range, the second harmonic of the first frequency range does not have that frequency is overlapping with the downlink signal of the second frequency range,
Without second harmonic is drawn away, directly moved end with the first non-moving end is turned on, uplink signal is sent by the first frequency range.
It is realized on the control process nature of control unit according to the frequency range of use, directly by modem in the present embodiment
30 are controlled according to the concrete condition of signal processing, in addition can also set tool of the independent control unit according to signal processing
Body situation is controlled, it might even be possible to directly generate low and high level signal according to the working condition of different frequency range by hardware circuit
Control the working condition of single-pole double-throw switch (SPDT) 61.
Single-pole double-throw switch (SPDT) 61 in this programme can more specifically select diode switch.Single-pole double-throw switch (SPDT) 61 simultaneously
Nor the unique selection in this programme, other such as triodes can also be realized to be switched on or switched off to cut to passage
It changes, and is respectively provided with smaller volume.In general, microelectric technique make single-pole double-throw switch (SPDT) 61 size (1mm ×
1mm) there was only 1/9th or so of the size (3mm × 3mm) of B8 power amplifiers 11 independent in Fig. 2, cost only have its five
/ mono- or so.
The relatively conventional combination of each frequency range is：First frequency range, the second frequency range and the 3rd frequency range be respectively B3 frequency ranges,
B8 frequency ranges and B4 frequency ranges, this is also the combination being described in Fig. 4.
The frequency of the downlink signal of B3 frequency ranges is 1805MHz-1880MHz；Uplink signal (the 880MHz- of B8 frequency ranges
Second harmonic 915MHz) is 1760MHz-1830MHz, and the two has overlapping in 1805MHz-1830MHz sections, if the two of B8
Subharmonic feeds back to the down going channel of B3, and the transmission of the downlink data of B3 can be interfered, and reduces speed of download.And under B4
The frequency of row signal is 2110MHz-2155MHz, and the second harmonic of B8 does not interfere with it, and second harmonic is guided into the passage of B4
The speed of download of B4 is not interfered with.
Another combination of each frequency range is：First frequency range, the second frequency range and the 3rd frequency range be respectively B4 frequency ranges,
B17 frequency ranges and B3 frequency ranges.
The realization principle of this combination is identical with the realization principle of previous combination.
Another realization method at harmonic wave consumption end is access ground terminal.The second non-moving end in Fig. 4 is grounded；Because connecing
Need to only Fig. 4 simple changes be can be realized by entering the mode of ground terminal, the process of the consumption of second harmonic with by the 3rd frequency range into
The mode of row consumption is similar, explanation of not mapping separately.
A kind of antenna assembly is additionally provided in the specific embodiment of the invention, is filled including previously described anti-harmonic wave interference
It puts.
