Background
The difficulty of two-path downlink carrier aggregation (hereinafter referred to as "carrier aggregation") is that two frequency bands work simultaneously, which brings great difficulty to the design of a radio frequency front end and an antenna. Generally, two frequency bands operating simultaneously use one of the two antennas. For a certain frequency band, the used antenna is fixed whether in a single-path working state or in a carrier aggregation working state with another frequency band.
Carrier aggregated antenna designs typically design antennas to include a first antenna and a second antenna. The working frequency of the first antenna is generally 1710 MHz-2690 MHz, and the working frequency of the second antenna is generally 699 MHz-960 MHz. However, for some carrier aggregation combination bands, for example, carrier aggregation bands of the japan docoo corporation, which include a higher-frequency if Band 1: 1920 MHz-2170 MHz and lower frequency intermediate frequency Band 21: 1448MHz to 1511MHz, wherein Band 21 is a frequency Band which is not covered by the antenna usually, and is only used by Docomo operators all over the world.

Detailed Description
In order that the objects, technical solutions and advantages of the present invention will become more apparent, the present invention will be further described in detail with reference to the accompanying drawings in conjunction with the following specific embodiments.
Fig. 1 shows a block diagram of a carrier aggregation radio frequency circuit 100 according to an embodiment of the invention.
As shown in fig. 1, the carrier aggregation rf circuit 100 includes a first antenna 101, a second antenna 102, a determining device 103, and a switching device 104. The carrier aggregation rf circuit 100 can operate in a carrier aggregation operating state of a first frequency band and a second frequency band.
According to an embodiment of the present invention, the determining device 103 may include, for example, a modem, and is configured to determine whether the carrier aggregation radio frequency circuit 100 is in a single-channel operating state of the first frequency band or in a carrier aggregation operating state of the first frequency band and the second frequency band.
According to an embodiment of the invention, the switching means 104 may for example comprise one or more switches. The switching device 104 switches the first frequency band to use the first antenna 101 or the second antenna 102 according to the working state determined by the determining device 103, so as to realize the transmission or reception of the signal.
Fig. 2a and 2b schematically show two operating states of the carrier aggregation radio frequency circuit 100 according to an embodiment of the present invention.
In this embodiment, the operating frequency of the first antenna includes a lower intermediate frequency band and a higher intermediate frequency band, and the operating frequency of the second antenna includes the lower intermediate frequency band and the lower frequency band. According to the embodiment of the invention, the intermediate frequency Band with lower frequency may include a Band 21 Band (1448MHz to 1511MHz), the intermediate frequency Band with higher frequency may include 1710MHz to 2170MHz, and the low frequency Band may include 824 to 960MHz, for example.
For example, the operating frequency of the first antenna of the carrier aggregation radio frequency circuit 100 may include 1448MHz to 2690MHz, and the operating frequency of the second antenna may include 699MHz to 1511 MHz.
The carrier aggregation rf circuit 100 may be in a single-channel operating state of the first frequency band or the second frequency band, or in a carrier aggregation operating state of the first frequency band and the second frequency band. According to the embodiment of the present invention, the first frequency Band may include an intermediate frequency Band with a lower frequency, for example, a Band 21 frequency Band (1448MHz to 1511MHz), and the second frequency Band may include an intermediate frequency Band with a higher frequency, for example, a Band1 frequency Band (1920 to 2170 MHz).
As shown in fig. 2a, when the determining device 103 determines that the carrier aggregation rf circuit 100 is in the single-channel operating state of the first frequency band, the switching device 104 switches the first frequency band to use the first antenna 101.
As shown in fig. 2b, when the determining device 103 determines that the carrier aggregation rf circuit 100 is in the carrier aggregation operating state of the first frequency band and the second frequency band, the switching device 104 switches the first frequency band to use the second antenna 102 and switches the second frequency band to use the first antenna 101.
During debugging, the intermediate frequency band with lower frequency is mainly put into the first antenna 101 for debugging, so that the efficiency of the intermediate frequency band meets the TRP/TIS requirement of the frequency band. In the second antenna 102, the tuning of the frequency band is also considered. In carrier aggregation, only the receiving part of the frequency band works, and the requirement on the antenna efficiency is slightly low. Therefore, the second antenna 102 with lower efficiency is accessed in the frequency band during carrier aggregation, and the antenna index requirement can be met. Meanwhile, the first antenna 101 is used in the intermediate frequency band with higher carrier aggregation frequency, so that the requirement of the first antenna on the antenna index can be met.
Therefore, when the carrier radio frequency aggregation circuit is in a single-path working state of an intermediate frequency band with lower frequency, the first antenna is used for transmitting/receiving, and the requirements of transmitting/receiving indexes can be well met. When the carrier radio frequency aggregation circuit is in a carrier aggregation working state of the intermediate frequency band with lower frequency and the intermediate frequency band with higher frequency, the intermediate frequency band with lower frequency uses the second antenna with lower working frequency for receiving, so that the requirement of the receiving performance index can be met, and the intermediate frequency band with higher frequency uses the first antenna with higher working frequency, so that the requirement of the receiving performance index can be well met.
Therefore, the second antenna does not need to be designed to simultaneously meet the requirements of transmitting and receiving indexes of the intermediate frequency band with lower frequency, the design and debugging difficulty can be obviously reduced, the circuit area is saved, and the manufacturing cost is reduced.
The carrier rf aggregation circuit 100 according to the embodiment of the present invention may also support other frequency band combinations, as described below.
Fig. 3a and 3b schematically show two operating states of the carrier aggregation radio frequency circuit 100 according to an embodiment of the present invention.
In this embodiment, the operating frequency of the first antenna of the carrier aggregation radio frequency circuit 100 may include a middle frequency band and a high frequency band (e.g., 2300MHz to 2690MHz) with higher frequencies, such as 1710MHz to 2690MHz, and the operating frequency of the second antenna may include a low frequency band and an ultra-low frequency band (e.g., 699MHz to 824MHz), such as 699MHz to 960 MHz. In this embodiment, the carrier aggregation radio frequency circuit 100 further includes a third antenna 105, and an operating frequency of the third antenna 105 is higher than an operating frequency of the first antenna, for example, a WIFI 2.4G antenna may be used.
The carrier aggregation rf circuit 100 may be in a single-channel operating state of the first frequency band or the second frequency band, and may be in a carrier aggregation operating state of the first frequency band and the second frequency band. According to an embodiment of the present invention, the first frequency band may include a high frequency band, for example, 2500MHz to 2690MHz, and the second frequency band may include a medium frequency band with a higher frequency, for example, 1710MHz to 1880 MHz.
As shown in fig. 3a, when the determining device 103 determines that the carrier aggregation rf circuit 100 is in the single-channel operating state of the first frequency band, the switching device 104 switches the first frequency band to use the first antenna 101.
As shown in fig. 3b, when the determining device 103 determines that the carrier aggregation rf circuit 100 is in the carrier aggregation operating state of the first frequency band and the second frequency band, the switching device 104 switches the first frequency band to use the third antenna 105, and the second frequency band uses the first antenna 101.
Therefore, when the carrier aggregation radio frequency circuit is in a single-path working state of a high-frequency band, the transmission/reception index requirement of the antenna can be met, and when the carrier aggregation radio frequency circuit is in a carrier aggregation working state of a high-frequency band and a medium-frequency band with higher frequency, the reception index requirement can be met. Meanwhile, the second antenna with lower working frequency does not need to be debugged to be suitable for both sending and receiving, so that the design and debugging difficulty can be obviously reduced, the circuit area is saved, and the manufacturing cost is reduced.
Fig. 4a and 4b schematically show two operating states of the carrier aggregation radio frequency circuit 100 according to an embodiment of the present invention.
In this embodiment, the operating frequency of the first antenna of the carrier aggregation radio frequency circuit 100 may include an intermediate frequency band and a high frequency band with higher frequencies, for example, 1710MHz to 2690MHz, and the operating frequency of the second antenna may include a low frequency band and an ultra-low frequency band, for example, 699MHz to 960 MHz. The carrier aggregation rf circuit 100 may be in a single-channel operating state in the first frequency band or the second frequency band, or in a carrier aggregation operating state in the first frequency band and the second frequency band. According to an embodiment of the present invention, the first frequency band may include a low frequency band, for example, 791MHz to 861MHz, and the second frequency band may include an ultra low frequency band, for example, 703MHz to 803 MHz.
As shown in fig. 4a, when the determining device 103 determines that the carrier aggregation rf circuit 100 is in the single-channel operating state of the first frequency band, the switching device 104 switches the first frequency band to use the second antenna 102.
As shown in fig. 4b, when the determining device 103 determines that the carrier aggregation rf circuit 100 is in the carrier aggregation operating state of the first frequency band and the second frequency band, the switching device 104 switches the first frequency band to use the first antenna 101, and the second frequency band uses the second antenna 102.
Therefore, when the carrier aggregation radio frequency circuit is in a single-path working state of a low-frequency band, the transmission/reception index requirement of the antenna can be met, and when the carrier aggregation radio frequency circuit is in a carrier aggregation working state of the low-frequency band and an ultra-low-frequency band, the reception index requirement can also be met. Meanwhile, the second antenna with lower working frequency does not need to be debugged to be suitable for both sending and receiving, so that the design and debugging difficulty can be obviously reduced, the circuit area is saved, and the manufacturing cost is reduced.
