Two kinds of main carrier frequencies are realized in the diversity reception of first frequency range downlink signal and the second frequency range downlink signal when existing descending carrier polymerization
The descending carrier of Duan Butong polymerize.
Specifically, by taking B2 frequency range and B4 frequency range as an example, the first SAW filter SAW1 and the filtering of the second surface acoustic wave
Device SAW2 is respectively filtered the first frequency range uplink signal and the first frequency range downlink signal, wherein the first phase shifter A1 is by setting
Setting the first preset value makes the first frequency range uplink signal, i.e. B2 TX signal (1850 ~ 1910MHz of frequency) passes through, end B2 TX with
Outer signal, the second phase shifter A2 make the first frequency range downlink signal, i.e. B2 RX signal (frequency by the way that the second preset value is arranged
1930 ~ 1990MHz) pass through, end the signal other than B2 RX, the corresponding third SAW filter SAW3 of B4 frequency range, third
Phase shifter A3, falling tone surface wave filter SAW4 and the 4th phase shifter A4 are similar.
If only needing B2 band operation, when not needing the descending carrier polymerization for realizing 2A-4A, first switch S1 and the is controlled
Three switch S3 closure, the first frequency range uplink signal B2 TX signal is by the first SAW filter SAW1 and the at this time
One phase shifter A1, because of the signal other than the first frequency range downlink signal B2 RX of the second phase shifter A2 cut-off, in the first frequency range
Row signal B2 TX signal only can reach antenna 10 by first switch S1 without going past third switch S3；And the first frequency range downlink
Signal B2 RX signal is received by antenna 10, by first switch S1, because the first phase shifter A1 ends the first frequency range uplink signal
Signal other than B2 TX only can be by the so the first frequency range downlink signal B2 RX signal is without going past the first phase shifter A1
Then three switch S3 pass through the second phase shifter A2 and the second SAW filter SAW2 enters back into wireless transceiver, if only needing
Second switch S2 and the 6th switch S6 closure is then controlled when B4 band operation, signal process is similar with B2 frequency range.
When if desired realizing the descending carrier polymerization of 2A-4A, with B2 frequency range for PCC(primary carrier
Component, that is, main carrier includes TX signal and RX signal), B4 frequency range is SCC(secondary carrier component
That is secondary carrier only includes RX signal) for, first switch S1, third switch S3 and the 6th switch S6 closure are controlled at this time,
First frequency range uplink signal B2 TX signal passes through the first SAW filter SAW1 and the first phase shifter A1, because second moves
Phase device A2 ends the signal other than the first frequency range downlink signal B2 RX, and the 4th phase shifter A4 ends the second frequency range downlink signal B4
Signal other than RX, so the first frequency range uplink signal B2 TX signal is without going past third switch S3 and the 6th switch S6, only meeting
Antenna 10 is reached by first switch S1；Antenna 10 receives the first frequency range downlink signal B2 RX and the second frequency range that carrier wave combines
Downlink signal B4 RX, wherein the first frequency range downlink signal passes through first switch S1, because the first phase shifter A1 ends the first frequency range
Signal other than uplink signal B2 TX, the 4th phase shifter A4 end the signal other than the second frequency range downlink signal B4 RX, so
First frequency range downlink signal B2 RX signal can only pass through third switch S3 without going past the first phase shifter A1 and the 6th switch S6
Then wireless transceiver is entered back by the second phase shifter A2 and the second SAW filter SAW2；Second frequency range downlink signal
B4 RX signal passes through first switch S1, because the first phase shifter A1 ends the first frequency range uplink signal B2 TX with external signal, the
Two phase shifter A2 end the signal other than the first frequency range downlink signal B2 RX, so the second frequency range downlink signal B4 RX signal is not
The first phase shifter A1 and third switch S3 can be passed through, only can then pass through the 4th phase shifter A4 and falling tone surface wave by the 6th
Filter SAW4 enters back into wireless transceiver, to realize using B2 frequency range as main carrier, B4 frequency range is under the 2A-4A of secondary carrier
Row carrier wave polymerizable functional reaches if necessary using B4 frequency range as main carrier, and the descending carrier that B2 frequency range is the 2A-4A of secondary carrier is poly-
Function is closed, then only needs to control second switch S2, the 4th switch S4 and the 5th switch S5 closure.Other frequency ranges such as B1 frequency
Section it is similar with the carrier aggregation signal transmission process of B3 frequency range, it is only necessary to adjust it is each filtering phase-shifting unit allow by signal frequently
Rate range can be realized.
The present invention realizes difference by using the combining form of SAW filter and phase shifter and multiple switch
The descending carrier of frequency range polymerize, with it is existing in such a way that four work devices realize carrier wave polymerization compared with, due to individual surface acoustic wave
The Insertion Loss of filter and phase shifter is less than the Insertion Loss of four work devices, improves loss, can also improve equipment power dissipation and equipment
Fever and the problems such as battery life, secondly, the cost of SAW filter and phase shifter to be far smaller than four work devices at
This, improves the manufacturing cost of equipment, the competitive advantage improved, if equipment needs while supporting 1A-3A and two kinds of 2A-4A
Descending carrier polymerization, then correspondingly increase by two groups of SAW filters and phase shifter again and switch, cost are much smaller than
The cost for increasing by four work devices improves the scalability of descending carrier polymerization radio circuit.
