Technical Field

The application relates to the technical field of mobile equipment, in particular to an antenna tuning switch controller, a communication module and a mobile terminal.

Background

As the frequency bands that a mobile terminal (e.g., a mobile phone) needs to support are increasing, the antenna routing space is decreasing, the antenna environment is more complex, and the bandwidth requirement is wider, and when the antenna is debugged, the low frequency part usually suffers from the problem of insufficient bandwidth, so an antenna tuner is generally added at the antenna location, and meanwhile, the corresponding relationship between different working frequency bands and different switch channels (hereinafter referred to as channels) is written in software, so as to switch different matching circuits for different frequency bands, thereby achieving the function of extending the antenna bandwidth.

However, in the prior art, in most cases, an antenna tuner (or antenna tuning switch) is used. The antenna tuner needs to be powered to operate and needs to be radio frequency driven to the corresponding configuration. In the antenna debugging stage, the logic configuration cannot be flexibly performed according to the antenna debugging result, recompilation may be performed through compiling software every time, and the time consumption is long; in the process of antenna debugging, the logic of the antenna tuning switch needs to be adjusted repeatedly so as to verify different logic corresponding relations. At present, the scheme of adjusting the antenna adjustment switch logic by using compiling software is not only complex and inconvenient to operate, but also consumes time and labor, and greatly influences the working efficiency.

In view of the above, it is an important issue for the relevant technicians and researchers to provide an antenna tuning switch controller to overcome the defects of complicated operation and low efficiency in the prior art.

Referring to fig. 1, an embodiment of the present application provides an antenna tuning switch controller 100, which is suitable for a communication module 200 (shown in fig. 2) of a mobile terminal 300 (shown in fig. 3).

Referring to fig. 2, the communication module 200 includes a baseband chip 211, at least one tuner 230 of the rf front end 220, and an antenna connected to the at least one tuner 230. Specifically, the communication module 200 mainly includes an antenna 240, a radio frequency front end 220, a radio frequency transceiver (not shown), and a baseband 210. A base band (base band) chip is disposed on the base band 210, and serves as a main chip of the mobile terminal 300 (e.g., a mobile phone). The baseband chip 211 is soldered to the main board PCB of the mobile phone. And the rf front end 220 is a communication element between the antenna 240 and the rf transceiver. The rf front end 220 may include a filter (not shown), a Low Noise Amplifier (LNA), a Power Amplifier (PA), a switch, and an antenna tuner (tuner). Wherein the filter is used to filter out noise, interference and unwanted signals, leaving only signals in the desired frequency range. For example, duplexers, triplexers, quadroplexers, and multiplexers generally employ a combination of filters, and filters used in mobile phones are mainly manufactured using both SAW (surface acoustic wave) and BAW (bulk acoustic wave) technologies. A power amplifier (not shown) is used to amplify the input signal when transmitting the signal so that the amplitude of the output signal is large enough for subsequent processing. The quality and efficiency of the power amplifier is critical to the signal integrity and battery life of the handset. A low noise amplifier (not shown) is used to amplify the received signal. The switch is used to switch between opening and closing by the switch to allow the signal to pass or not pass. The switches are for example: single-pole single-throw, single-pole double-throw, multi-pole multi-throw switches. The tuner 230 is located between the antenna 240 and the end of the signal path for matching the electrical characteristics of the two sides to each other, thereby improving power transfer therebetween.

In the present embodiment, the antenna tuning switch controller 100 is respectively connected to the baseband chip 211 and the at least one tuner 230. The antenna tuning switch controller 100 is suitable for an antenna debugging stage, and can effectively overcome the defects of complex operation and low efficiency in the prior art.

Specifically, as shown in fig. 1, the antenna tuning switch controller 100 includes a control panel 101. At least one tuner selection unit 110 is disposed on the control panel 101. Generally, the tuner selecting unit 110 is plural. In the present embodiment, the number of the tuner selecting units 110 is four. Of course, in other embodiments, the number of the tuner selecting units 110 is not limited to four, for example, three, five, six, etc.

Each tuner selection unit 110 includes at least one channel subunit 120. By this, the channel subunit 120 is plural. In the present embodiment, the number of the channel subunits 120 is four. Of course, in other embodiments, the number of the channel subunits 120 is not limited to four, such as three, five, six, etc.

In some embodiments of the present application, the number of the tuner selecting units 110 is equal to or greater than the number of the tuners 230. In some embodiments of the present application, the number of the channel subunits 120 is equal to or greater than the number of channels (not shown) in the tuner 230. It should be noted that the number of the tuners 230 is determined according to the design of the antenna trace, some of the tuners 230 may be disposed at the ends of the antenna trace, some of the tuners 230 may be disposed in the middle of the antenna trace, and some of the tuners 230 may be disposed on the feed line. In addition, different antennas may use different tuners 230. And the number of channels is determined by the material of the tuner 230.

Further, in some embodiments, the number of the tuner selecting units 110 may correspond to the number of tuners, and the number of the channel sub-units 120 may correspond to the number of channels in the tuner 230. Of course, in some other embodiments, the tuner selection unit 110 and its channel subunit 120 may not correspond to the tuner and its channel.

Further, when the communication module 200 uses only three tuners 230 and four tuner selecting units 110 (e.g., the first tuner selecting unit 111, the second tuner selecting unit 112, the third tuner selecting unit 113, and the fourth tuner selecting unit 114) are provided on the control panel 101, the last tuner selecting unit 110 on the control panel 101 is set to be inoperable.

Also, when the tuner 230 actually used has only three channels (not shown), and the number of the channel sub-units 120 in the tuner selection unit 110 on the control panel 101 is four, the last channel sub-unit in the tuner selection unit 110 is set to be inoperable.

In some implementations of the present application, the number of channel subunits 120 in each tuner selection unit 110 may be the same. As shown in fig. 1, the number of channel subunits 120 in each tuner selection unit 110 is four. In other embodiments of the present application, the number of channel subunits 120 may also be different from each other. It should be noted that the number of channel subunits 120 is determined according to the material of the corresponding tuner 230.

With continued reference to fig. 1, each of the channel sub-units 120 is configured to determine a tuner 230 corresponding to the tuner selection unit 110 and an antenna 240 corresponding to the tuner 230.

That is, a plurality of tuner selection units 110 are provided on the control panel 101. Each tuner selecting unit 110 corresponds to a menu. As in the present embodiment, there are four tuner selecting units 110 on the control panel 101, which is equivalent to having four menus. Since each tuner selecting unit 110 has four channel subunits 120, each menu correspondingly displays four options, respectively representing channel 1, channel 2, channel 3, channel 4, i.e. corresponding to the four channel subunits 120 (

reference numerals

121, 122, 123, 124 shown in fig. 1). When a certain option under one menu is selected, it indicates switching to the corresponding channel subunit 120 in the corresponding tuner selection unit 110, and also indicates switching to the corresponding channel. For example, selecting the channel 2 option in the first tuner selection unit 111 on the control panel 101 indicates that the second channel sub-unit 122 of the first tuner selection unit 111 is selected (i.e., the second channel sub-unit 122 receives a selected command), which indicates that the channel identified as channel 2 is to be forcibly switched. Further, the channel corresponding to the second channel sub-unit 122 in the first tuner selecting unit 111 is turned on. Since each of the channel subunits 120 is used to determine the tuner 230 corresponding to the tuner selection unit 110 and the antenna 240 corresponding to the tuner 230, the selection of the channel subunit 120 on the control panel 101 also actually determines the antenna matching corresponding to the selected channel subunit 120, which can be applied to the corresponding operating frequency band.

Note that, the selection of the tuner selection unit means that the tuner selection unit receives (or acquires) an external trigger instruction (the same applies hereinafter). Similarly, the selection of a channel subunit indicates that the channel subunit receives (or fetches) an external trigger instruction (the same applies hereinafter). The trigger command may be a switch command.

In addition, in practical operation, when one tuner selecting unit 110 is used and the parameter related to the tuner selecting unit 110 is configured to be normal, one of the channel sub-units 120 in the tuner selecting unit 110 is selected by default. Of course, in some embodiments, when multiple tuner selection units 110 are used and the parameters associated with the tuner selection units 110 are configured to be normal, the corresponding channel sub-unit 120 in each tuner selection unit 110 may be selected at the same time. Note that the tuner 230 corresponding to the tuner selection unit 110 is of a material capable of supporting this configuration. Thus, different tuner selection units 110 (and corresponding tuners 230) can operate in the same communication band.

In addition, in some embodiments of the present application, each tuner selecting unit 110 is independent from each other and different from each other. When the first switch 102 is enabled (refer to the following description), at any time, multiple tuner selection units and their corresponding tuners may be allowed to operate simultaneously and in the same communication band. Also, the currently operating channel sub-units 120 in different tuner selection units 110 may be the same or different. When the first switch 102 is disabled (see below), it may also allow multiple tuners to operate simultaneously and in the same communication band.

In some embodiments of the present application, a first switch 102 is disposed on the control panel 101, and the first switch 102 is used for enabling or disabling the baseband chip 211 to be connected to the at least one tuner 230 through the antenna tuning switch controller 100. Specifically, the first switch 102 has two options, e.g., Enable/Disable (i.e., Enable/Disable). When the Enable option is selected (i.e. when the first switch 102 receives the enabling command), the tuner no longer determines which channel to turn on according to the current communication frequency band (or called operating frequency band), but determines the turn-on of the corresponding channel according to the command obtained by the antenna tuning switch controller 100 (i.e. the selection of the tuner selecting unit 110 and the channel sub-unit 120 thereof on the control panel 101). That is, when the Enable option is selected, the first switch 102 prohibits the baseband chip 211 from being connected to the tuner 230 through the antenna tuning switch logic module 250, but allows the baseband chip 211 to be connected to the tuner 230 through the antenna tuning switch controller 100. The antenna tuning switch logic module 250 implements control logic based on the current operating frequency band, which will be further described below.

In some embodiments of the present application, each of the tuner selecting units 110 is connected to the baseband chip 211 through N control lines 260, and the baseband chip 211 is configured to control M channel subunits 120 in each of the tuner selecting units 110 through the N control lines 260, where M and N are positive integers, and M is less than or equal to 2N. Further, the switching between M channel sub-units 120 in the same one of said tuner selection units 110 is controlled by a combined variation of a first level and a second level of N control lines 260, where M is a positive integer larger than 1.

Specifically, in the present embodiment, the number of the control lines 260 of each tuner selecting unit 110 is two, and each of the control lines 260 has a first level (for example, a high level, without limitation) and a second level (for example, a low level, without limitation), and the number of the channel sub-units 120 in each tuner selecting unit 110 is four, and thus, by a combination change of the first level and the second level of the two control lines 260, it is possible to support control of four different channel sub-units 120. In addition, in this embodiment, the control line 260 is a GPIO control line, the GPIO control line is connected to the baseband chip 211, and the baseband chip 211 can control to output two levels (high level and low level) so that each GPIO control line has two level states, thereby being capable of supporting control of different channel sub-units 120. If two GPIO control lines are used, control of four or less channel subunits 120 may be achieved. If one GPIO control line is used, control of two channel sub-units 120 or less can be achieved. If three GPIO control lines are used, control of less than or equal to six channel subunits 120 may be achieved, and so on. Of course, in some other embodiments, the control line 260 may also use a control line based on a Mobile Industry Processor Interface (MIPI) protocol, which may implement more line states, so as to meet the requirement of supporting more channel subunits 120.

Referring to fig. 2, an embodiment of the present application further provides a communication module 200, which is suitable for a mobile terminal 300, where the communication module 200 includes: an antenna tuning switch controller 100 and an antenna tuning switch logic module 250.

The structure and function of the antenna tuning switch controller 100 are as described above, and are not described herein again.

The antenna tuning switch logic module 250 is respectively connected to the baseband chip 211 and the at least one tuner 230. The antenna tuning switch logic module 250 is configured to allow the baseband chip 211 to be connected to the corresponding tuner 230 through the antenna tuning switch logic module according to the current communication frequency band when the baseband chip 211 is prohibited from being connected to the at least one tuner 230 through the antenna tuning switch controller 100 by the first switch 102 on the control panel 101. That is, when the Disable option is selected (i.e., when the first switch 102 receives the Disable instruction), the tuner 230 determines to turn on the corresponding channel according to the current communication band (or operating band), instead of determining to turn on the corresponding channel according to the instruction obtained by the antenna tuning switch controller 100 (i.e., the selection of the tuner selecting unit 110 and the channel sub-unit 120 on the control panel 101). Normally, the first switch 102 is set to Disable option as default state.

Referring to fig. 3, an embodiment of the present application further provides a mobile terminal 300, where the mobile terminal 300 includes a communication module 200. The structure and function of the communication module 200 are as described above, and are not described herein again.

In some embodiments of the present application, the mobile terminal 300 further includes a first memory 301, and a control line level parameter table (not shown) is stored in the first memory 301, and the control line level parameter table is used to record a relationship between the channel subunit 120, an operating frequency band of the antenna, and level parameters of control lines respectively connected to the baseband chip 211 and the channel subunit 120.

Specifically, the level parameters of the control lines are respectively set corresponding to the operating frequency band of the antenna 240 and the channel subunit 120. For example, when the first tuner selecting unit 111 operates in the communication band B5, the level parameters on the two GPIO control lines (i.e., the level parameters of the control lines) of the first tuner selecting unit 111 are set to 0 and 0, respectively. When the first tuner selecting unit 111 operates in the communication band B8, the level parameters on the two GPIO control lines (i.e., the level parameters of the control lines) of the first tuner selecting unit 111 are set to 0 and 1, respectively. Therefore, the corresponding channels required to be used by each communication band, i.e., the level parameters used on each corresponding GPIO control line, are all preset in the first memory 301 of the mobile terminal 300.

In some embodiments of the present application, the mobile terminal 300 further includes a second memory 302, and a tuning switch mapping table (not shown) is stored in the second memory 302. In some implementations of the present application, the second memory 302 may also be the first memory 301, that is, the tuning switch mapping table may also be stored in the first memory 301.

The tuning switch mapping table is used to map the relationship between the tuner selecting unit 110 and the corresponding tuner 230, and the relationship between the channel subunit 120 and the corresponding channel in the tuner 230, which is equivalent to that the corresponding relationship between the tuner selecting unit 110 and its channel subunit 120, and the tuner 230 and its channel is preset on the control panel 101.

Further, the mapping relationship of the trigger command of the channel subunit 120 is also recorded in the tuning switch mapping table. When the channel subunit 120 is selected (which is equivalent to the channel subunit 120 receiving the trigger command for channel switching), the mobile terminal 300 can automatically switch the current channel to the channel which is preset and corresponds to the channel subunit 120.

Therefore, when a certain channel needs to be used in the antenna debugging stage, the test can be performed only by setting the corresponding channel subunit 120 on the control panel 101, so that the workload of recompiling software can be avoided, the time consumption is reduced, the operation is simplified, and the working efficiency is improved.

Referring to fig. 4, in other embodiments of the present application, the mobile terminal 400 may further include the following components: memory 420 may be used to store software programs and modules. The processor 480 executes various functional applications and data processing by executing software programs and modules stored in the memory 420. The memory 420 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 420 may further include memory located remotely from the processor 480, which may be connected to the mobile terminal 400 via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The input unit 430 may be used to receive input numeric or character information and generate keyboard, mouse, joystick, optical or trackball signal inputs related to user settings and function control. In particular, the input unit 430 may include a touch-sensitive surface 431 as well as other input devices 432. The touch-sensitive surface 431, also referred to as a touch screen or touch pad, may collect touch operations by a user on or near it (e.g., operations by a user on or near the touch-sensitive surface 431 using a finger, a stylus, or any other suitable object or attachment), and drive the corresponding connection device according to a predetermined program. Alternatively, the touch sensitive surface 431 may comprise both a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 480, and receives and executes commands sent from the processor 480. In addition, the touch-sensitive surface 431 may be implemented in various types, such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 430 may include other input devices 432 in addition to the touch-sensitive surface 431. In particular, other input devices 432 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

The display unit 440 may be used to display information input by or provided to the user and various graphical user interfaces of the mobile terminal 400, which may be made up of graphics, text, icons, video, and any combination thereof. The Display unit 440 may include a Display panel 441, and optionally, the Display panel 441 may be configured in the form of an LCD (Liquid Crystal Display), an OLED (Organic Light-Emitting Diode), or the like. Further, the touch-sensitive surface 431 may overlay the display panel 441, and when a touch operation is detected on or near the touch-sensitive surface 431, the touch operation is transmitted to the processor 480 to determine the type of the touch event, and then the processor 480 provides a corresponding visual output on the display panel 441 according to the type of the touch event. Although in FIG. 4 the touch sensitive surface 431 and the display panel 441 are two separate components to implement input and output functions, in some embodiments the touch sensitive surface 431 and the display panel 441 may be integrated to implement input and output functions.

The mobile terminal 400 may also include at least one sensor 450, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that may adjust the brightness of the display panel 441 according to the brightness of ambient light, and a proximity sensor that may turn off the display panel 441 and/or a backlight when the mobile terminal 400 is moved to the ear. As one of the motion sensors, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when the mobile phone is stationary, and can be used for applications of recognizing the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which may be further configured on the mobile terminal 400, detailed descriptions thereof are omitted.

The audio circuit 460, speaker 461, microphone 462 may provide an audio interface between a user and the mobile terminal 400. The audio circuit 460 may transmit the electrical signal converted from the received audio data to the speaker 461, and convert the electrical signal into a sound signal for output by the speaker 461; on the other hand, the microphone 462 converts the collected sound signal into an electric signal, which is received by the audio circuit 460 and converted into audio data, which is then processed by the audio data output processor 480, and then transmitted to, for example, another terminal via the RF circuit 410, or output to the memory 420 for further processing. The audio circuit 460 may also include an earbud jack to provide communication of a peripheral headset with the mobile terminal 400.

The mobile terminal 400, which may assist the user in e-mail, web browsing, and streaming media access, etc., through the transmission module 470 (e.g., a Wi-Fi module), provides the user with wireless broadband internet access. Although fig. 4 shows the transmission module 470, it is understood that it does not belong to the essential constitution of the mobile terminal 400 and may be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 480 is a control center of the mobile terminal 400, connects various parts of the entire mobile terminal using various interfaces and lines, and performs various functions of the mobile terminal 400 and processes data by operating or executing software programs and/or modules stored in the memory 420 and calling data stored in the memory 420, thereby integrally monitoring the mobile terminal. Optionally, processor 480 may include one or more processing cores; in some embodiments, processor 480 may integrate an application processor, which primarily handles operating systems, user interfaces, applications, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into processor 480.

The mobile terminal 400 may also include a power supply 490 (e.g., a battery) for powering the various components, which in some embodiments may be logically connected to the processor 480 via a power management system that may be configured to manage charging, discharging, and power consumption.
