Description
Technical field
The present invention relates to fields of communication technology, and in particular to a kind of radio-frequency unit and communication equipment.
Background technology
At present, in order to increase communication bandwidth, higher user data throughput is realized, in advanced Long Term Evolution
In (Long Term Evolution-Advanced, LTE-A), carrier aggregation (Carrier Aggregation, CA) is employed
Technology.Carrier aggregation is a kind of broader frequency range by the way that the frequency spectrum resource of different frequency range to be merged into one, to increase signal
Transmission bandwidth, the technology for improving message transmission rate.
The frequency range of LTE system is divided into low frequency (Low Band, LB), intermediate frequency (Middle Band, MB) and high frequency (High
Band, HB).The carrier aggregation signal of multicarrier received by antenna, which is generally required, to be divided to by band separation such as LB, MB, HB
Corresponding radio-frequency module is sent in corresponding frequency range, after the operations such as filtered again, amplification of carrier signal in each frequency range to do
Corresponding processing.
Fig. 1 show a kind of structure diagram of radio-frequency unit of prior art offer.As shown in Figure 1, the radio-frequency unit
Including 22 two frequency dividers of the first frequency divider 21 and the second frequency divider, the first frequency divider 21 is coupled to antenna 10, the second frequency divider
22 are coupled to the first frequency divider 21.When the radio-frequency unit is used as radio frequency receiver, the first frequency divider 21 is used to connect from antenna 10
Radiofrequency signal is received, and the HB in radiofrequency signal and MB and LB are distinguished；Second frequency divider 22 is used for will be through the first frequency divider 21
Signal after frequency dividing is divided into MB and LB.Then when carrying out 3CA LB+MB+HB operations, the radiofrequency signal that antenna 10 receives is first through the
One frequency divider 21 separates two paths of signals, wherein being all the way HB signals, the HB signals are coupled to more than the first of the first frequency divider 21
Path multiplexer (Multiplexer, MUX) 31 is switched to corresponding frequency range, then at least one first filter 41 through specific frequency
At least one first radio-frequency module 51 can be sent to after filtering and carries out signal processing；Another way signal is again through the second frequency divider 22
It is divided into MB signals and LB signals, wherein coupled the second multiplexer 32 to the second frequency divider 22 of MB signals after being divided
Corresponding frequency range is switched to, then at least one second can be sent to after at least one second filter 42 of specific frequency filters
Radio-frequency module 52 carries out signal processing, and then the coupled third multiplexer 33 to the second frequency divider 22 is switched to correspondence to LB signals
Frequency range, then through specific frequency at least one third wave filter 43 filtering after can be sent at least one third radio-frequency module
53 carry out signal processing.For another example, when carrying out 2CA LB+MB operations, radiofrequency signal that antenna 10 receives is also required to first pass through the
One frequency divider 21 carries out divide operation through the second frequency divider 22 again, then separates MB signals and LB signals, MB signals/LB signals point
Corresponding frequency range is not switched to, then through at least one of specific frequency through 32/ third multiplexer 33 of the second multiplexer
After 42/ at least one third wave filter 43 of second filter is filtered, it is finally sent at least one second radio-frequency module 52/
At least one third radio-frequency module 53 carries out signal processing.Not believe it is carrier aggregation signal when radio frequency, when not needing to do CA operations,
If LTE system is in the case where using LB frequency ranges, radiofrequency signal can equally pass through the first frequency divider 21 and the second frequency divider 22, so
Enter third multiplexer 33 afterwards, the switch through third multiplexer 33 switches to corresponding frequency range, then through at least one the
After the filtering of three wave filters 43, finally it is sent at least one third radio-frequency module 53 and carries out signal processing.
It follows that during using radio-frequency unit shown in FIG. 1, regardless of whether carrying out CA operations, radiofrequency signal all has to
By the first frequency divider 21 and the second frequency divider 22, therefore loss can be caused to rise, no matter the radio-frequency unit is used as radio-frequency transmissions
Device or receiver, transmitting and the performance received can all be affected by this and be declined.
