Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a radio frequency circuit and electronic device. Background Technology

[0002] With the advent of 5G in mobile terminals, network deployment has become more flexible. SA (Standalone) and NSA (Non-Standalone) are the two main 5G network deployment modes. SA mode is a standalone network, meaning one core network is paired with one type of base station. 5G technology is used from the core network to the base stations, providing low latency and a better network experience. NSA mode, on the other hand, is a non-standalone network, where 5G base stations are deployed on top of 4G infrastructure, using the 4G core network. The 5G network is achieved by adding 5G base stations, a method that allows for 5G network construction at a lower cost. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this disclosure, the solutions of the embodiments of this disclosure will be further described below. It should be noted that, unless otherwise specified, the embodiments of this disclosure and the features within them can be combined with each other.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the embodiments of this disclosure, but the embodiments of this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the embodiments of this disclosure, and not all embodiments.

[0022] Globally, 5G network deployment is at different stages. Some regions may have already established complete 5G core networks and radio access networks, achieving SA mode, while other regions may still be deploying in NSA mode using existing 4G infrastructure. Therefore, terminal devices need to be able to adapt to these two different network architectures to ensure stable 5G connectivity everywhere. Different operators may choose different 5G deployment strategies based on their own resources and technical plans. Some operators may first adopt NSA mode to quickly launch 5G services and then gradually transition to SA mode, while others may directly choose SA mode. To meet the needs of different operators, terminal products must be flexible and able to switch between NSA and SA modes.

[0023] In view of this, one embodiment of the present disclosure provides a radio frequency circuit, such as Figure 1 As shown, it includes a first power supply 11, a first conversion module 21, a second conversion module 22, a first transmission module TX1, a second transmission module TX2, a first amplification unit group PA1, and a second amplification unit group PA2, each amplification unit group including at least one amplification unit.

[0024] The first amplification unit group PA1 and the second amplification unit group PA2 support different frequency bands, thus enabling amplification of signals in different frequency bands and realizing NSA networking mode. In one specific embodiment, the first amplification unit group PA1 and the second amplification unit group PA2 may support completely different frequency bands. For example, the first amplification unit group PA1 supports the LB (Low Band) frequency band, and the second amplification unit group PA2 supports the HB (High Band) frequency band. In another specific embodiment, the first amplification unit group PA1 and the second amplification unit group PA2 may support partially the same frequency band. For example, the first amplification unit group PA1 supports the MHB (Mid-High Band) frequency band, and the second amplification unit group PA2 supports the HB frequency band.

[0025] Specifically, such as Figure 1 As shown, the first conversion module 21, the second conversion module 22, the first transmission module TX1, and the second transmission module TX2 are all located in the transceiver chip IC. The first conversion module 21 and the first transmission module TX1 can communicate with each other through other circuit structures or modules in the transceiver chip IC, and the second conversion module 22 and the second transmission module TX2 can communicate with each other through other circuit structures or modules in the transceiver chip IC.

[0026] The first transmitting module TX1 and the first conversion module 21 work together. When the first conversion module 21 is connected to the first power supply 11, the amplification unit group connected to the first power supply 11 is connected to the first transmitting module TX1. This amplification unit group can then receive the power signal provided by the first power supply 11 and the transmission signal provided by the first transmitting module TX1, and amplify and output the transmission signal provided by the first transmitting module TX1. In other words, when the amplification unit group connected to the first power supply 11 is the first amplification unit group, it can receive the power signal provided by the first power supply 11 and the transmission signal provided by the first transmitting module TX1; when the amplification unit group connected to the first power supply 11 is the second amplification unit group, it can receive the power signal provided by the first power supply 11 and the transmission signal provided by the first transmitting module TX1. When this amplification unit group can achieve signal amplification in the 5G band, the radio frequency circuit can achieve SA networking mode; or, in other embodiments, even if the amplification unit group cannot support signal amplification in the 5G band, it can still support frequency bands related to network standards such as LTE and NR, ensuring basic communication performance.

[0027] Furthermore, the second transmitting module TX2 and the second conversion module 22 work together. When the second conversion module 22 is connected to the first power supply 11, the amplification unit group connected to the first power supply 11 is connected to the second transmitting module TX2. This amplification unit group can then receive the power signal provided by the first power supply 11 and the transmitting signal provided by the second transmitting module TX2, and amplify and output the transmitting signal provided by the second transmitting module TX2. In other words, when the amplification unit group connected to the first power supply 11 is the second amplification unit group, it can receive the power signal provided by the first power supply 11 and the transmitting signal provided by the second transmitting module TX2; when the amplification unit group connected to the first power supply 11 is the first amplification unit group, it can receive the power signal provided by the first power supply 11 and the transmitting signal provided by the second transmitting module TX2. When this amplification unit group can achieve signal amplification in the 5G band, the radio frequency circuit can achieve SA networking mode; or, in other embodiments, even if the amplification unit group cannot support signal amplification in the 5G band, it can still support frequency bands related to network standards such as LTE and NR, ensuring basic communication performance.

[0028] In one specific embodiment, the first power supply 11 can be connected to the first conversion module 21, the second conversion module 22, the first amplification unit group PA1, and the second amplification unit group PA2 simultaneously. At this time, both the first amplification unit group PA1 and the second amplification unit group PA2 receive the power signal provided by the first power supply 11 and amplify and output the transmission signals provided by the first transmission module TX1 and the second transmission module TX2 respectively. Thus, the entire radio frequency circuit can amplify signals of two frequency bands simultaneously. When the first amplification unit group PA1 and the second amplification unit group PA2 can respectively realize the signal amplification of the 5G frequency band and the 4G frequency band, the radio frequency circuit can realize the NSA networking mode.

[0029] The radio frequency (RF) circuit provided in this disclosure, through its NSA and SA compatibility design, enables terminal electronic devices to meet different communication needs, better cope with future network mode changes, extend product lifespan, reduce user replacement frequency, and improve user experience. When NSA mode is not required, the RF circuit provided in this disclosure can be used in conjunction with a conversion module and a transmission module, using only one power supply to power multiple amplification unit groups, thereby meeting the amplification requirements of multiple frequency band signals, reducing circuit size and manufacturing costs. Furthermore, based on its compatibility with both NSA and SA networking modes, the RF circuit provided in this disclosure further enhances the flexibility of the device during communication by enabling flexible switching between NSA and SA modes through the cooperation between the conversion module and the transmission module.

[0030] It is understood that the above embodiments of this disclosure take two conversion modules, two transmission modules and two amplification unit groups as examples. In other embodiments, the above radio frequency circuit may include N conversion modules, N transmission modules and N amplification unit groups to be compatible with signals of more frequency bands, all of which are within the protection scope of the embodiments of this disclosure.

[0031] In one specific embodiment, such as Figure 2 As shown, the radio frequency circuit also includes a radio frequency device group 30 and an antenna ANT; the radio frequency device group 30 includes at least two radio frequency device units 31; each amplification unit group is connected to the antenna ANT through a corresponding radio frequency device unit 31. The above-mentioned transmitted signal is amplified by the amplification unit group and then input to the radio frequency device unit 31, which then transmits it to the antenna ANT, and the antenna ANT then transmits it to the outside.

[0032] Specifically, the aforementioned radio frequency device unit 31 may include filters, radio frequency switching devices, etc. The radio frequency device units 31 connected to different amplification unit groups may be the same or different.

[0033] In embodiments of the back-end devices of other amplification unit groups not shown in this disclosure, all may include Figure 2 The radio frequency device group 30 and the antenna ANT shown in the embodiment are all within the protection scope of this disclosure and will not be described in detail again.

[0034] In some embodiments, such as Figure 3 As shown, the radio frequency circuit provided in this embodiment of the present disclosure further includes a second power supply 12. When the first conversion module 21 is connected to the second power supply 12, the amplification unit group connected to the second power supply 12 is connected to the first transmitting module TX1; and when the second conversion module 22 is connected to the second power supply 12, the amplification unit group connected to the second power supply 12 is connected to the second transmitting module TX2.

[0035] Specifically, the first transmitting module TX1 and the first conversion module 21 are used together. That is, when the first conversion module 21 is connected to the second power supply 12, the amplification unit group connected to the second power supply 12 is connected to the first transmitting module TX1. Thus, the amplification unit group can simultaneously receive the power signal provided by the second power supply 12 and the transmitting signal provided by the first transmitting module TX1, and amplify and output the transmitting signal provided by the first transmitting module TX1.

[0036] Furthermore, the second transmitting module TX2 and the second conversion module 22 are used together. That is, when the second conversion module 22 is connected to the second power supply 12, the amplification unit group connected to the second power supply 12 is connected to the second transmitting module TX2. Thus, the amplification unit group can simultaneously receive the power signal provided by the second power supply 12 and the transmitting signal provided by the second transmitting module TX2, and amplify and output the transmitting signal provided by the second transmitting module TX2.

[0037] exist Figure 3 In the illustrated embodiment, because more power modules are included, each amplification unit group can receive power from a power module independently, ensuring stable power supply.

[0038] In some embodiments, the first power supply 11 and the second power supply 12 have average power tracking and / or envelope tracking functions, thereby tracking the power changes of the RF amplification unit group, adjusting the power supply voltage of the amplification unit group in real time, and improving the operating efficiency of the amplification unit group. Since each power supply can only track the power of one amplification unit group when implementing the above-mentioned average power tracking and / or envelope tracking functions, setting a separate power supply for each amplification unit group enables the tracking of the power of each amplification unit group, thereby improving the operating efficiency of all amplification unit groups.

[0039] Specifically, both the first power supply 11 and the second power supply 12 include a first envelope tracking output terminal HBW, a second envelope tracking output terminal LBW, and an average power tracking output terminal APT. The first envelope tracking output terminal HBW enables wideband envelope tracking, the second envelope tracking output terminal LBW enables narrower frequency band envelope tracking, and the average power tracking output terminal APT can dynamically adjust the supply voltage of the amplification unit group based on the average output power of the amplification unit group using an algorithm. Those skilled in the art can connect the first amplification unit group PA1 and the second amplification unit group PA2 to different ports of the first power supply 11 and the second power supply 12 according to the specific implementation requirements; no further limitations are imposed here.

[0040] In a specific implementation, the transceiver IC also includes a baseband chip. The baseband chip generates an envelope control signal and provides it to the aforementioned conversion module. The conversion module then provides the envelope control signal to the power supply, enabling the power supply to use the envelope control signal to achieve envelope tracking.

[0041] In some embodiments, such as Figure 4 As shown, the radio frequency circuit provided in this embodiment of the present disclosure further includes a first switch S1; the first conversion module 21 and the second conversion module 22 are both connected to the first power supply 11 and the second power supply 12 through the first switch S1.

[0042] Specifically, the first switch S1 can be a multi-pole multi-throw switch, which includes multiple external ports for connecting multiple modules in the radio frequency circuit of this embodiment. Its internal switching circuit can electrically connect the multiple external ports based on external control signals (which can be provided by a transceiver chip IC) to realize the connection between the multiple modules. The second switch in the following embodiments is similar to the third switch and will not be described again.

[0043] In specific implementation, the first conversion module 21 can be connected to the first power supply 11 through the first switch S1, and the second conversion module 22 can be connected to the second power supply 12 through the first switch S1; or, the first conversion module 21 can be connected to the second power supply 12 through the first switch S1, and the second conversion module 22 can be connected to the first power supply 11 through the first switch S1. The first switch S1 can realize flexible connection between multiple conversion modules and multiple power supplies, thereby improving the overall flexibility of the circuit.

[0044] In some embodiments, such as Figure 5 As shown, the radio frequency circuit provided in this embodiment further includes a second switch S2. Both the first transmitting module TX1 and the second transmitting module TX2 are connected to the first amplification unit group PA1 and the second amplification unit group PA2 via the second switch S2.

[0045] In specific implementation, the first transmitting module TX1 can be connected to the first amplification unit group PA1 through the second switch S2, and the second transmitting module TX2 can be connected to the second amplification unit group PA2 through the second switch S2; or, the first transmitting module TX1 can be connected to the second amplification unit group PA2 through the second switch S2, and the second transmitting module TX2 can be connected to the first amplification unit group PA1 through the second switch S2. The second switch S2 enables flexible connection between multiple transmitting modules and multiple amplification unit groups, allowing each transmitting module to flexibly select the amplification unit group of the required frequency band for signal amplification, thereby improving the overall flexibility of the circuit.

[0046] In some embodiments, such as Figure 6 As shown, the radio frequency circuit provided in this embodiment of the present disclosure further includes a third switch S3. The first power supply 11 and the second power supply 12 are both connected to the first amplification unit group PA1 and the second amplification unit group PA2 through the third switch S3.

[0047] In specific implementation, the first power supply 11 can be connected to the first amplification unit group PA1 through the third switch S3, and the second power supply 12 can be connected to the second amplification unit group PA2 through the third switch S3; or, the first power supply 11 can be connected to the second amplification unit group PA2 through the third switch S3, and the second power supply 12 can be connected to the first amplification unit group PA1 through the third switch S3. The third switch S3 enables flexible connection between multiple power supplies and multiple amplification unit groups, allowing each amplification unit group to flexibly select a power supply for power, thereby improving the overall flexibility of the circuit.

[0048] In other embodiments, such as Figure 7 As shown, the radio frequency circuit provided in this embodiment of the present disclosure further includes a third switch S3; the first power supply 11 and the second power supply 12 are both connected to the second amplification unit group PA2 through the third switch S3, and the first power supply 11 is connected to the first amplification unit group PA1.

[0049] Compared to Figure 6 The embodiment shown, Figure 7The illustrated embodiment simplifies the circuit topology. Specifically, in NSA networking mode, the first power supply 11 supplies power to the first amplification unit group PA1, while the second power supply 12 supplies power to the second amplification unit group PA2 through the third switch S3. The first amplification unit group PA1 and the second amplification unit group PA2 can amplify and output signals of different frequency bands. In SA networking mode, if the first amplification unit group PA1 is selected to amplify and output signals of a single frequency band, the first power supply 11 still supplies power to the first amplification unit group PA1. If the second amplification unit group PA2 is selected to amplify and output signals of a single frequency band, then the power supply can be flexibly selected from the first power supply 11 and the second power supply 12 to supply power to the second amplification unit group PA2, ensuring a certain degree of flexibility while reducing circuit complexity.

[0051] In some embodiments, such as Figure 9 As shown, the second amplification unit group PA2 includes two amplification units PA0 connected in series.
