Detailed implementation manners

[0032] In order to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0033] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0034] First, a brief description will be given of the related technologies and their existing defects, as well as the solutions of the embodiments of the present disclosure proposed for improving them.

[0035] Regarding the technical problems described in the background art, the applicant has found through research that in the CA scenario, if a mobile terminal needs to transmit multi-band signals such as intermediate frequency signals and high-frequency signals outward, one way is to set two antennas inside the mobile terminal, one antenna for transmitting intermediate frequency signals and the other antenna for transmitting high-frequency signals. However, due to the limitation of the screen structure such as the black edge in the mobile terminal, the available antenna clearance area of the mobile phone is often small, and this way requires more antenna routing area, so this dual-antenna design is difficult to implement. Therefore, another way is to use a combiner to connect a single antenna to save the antenna routing area.

[0036] Exemplarily, Figure 1 FIG. is a schematic structural diagram of a radio frequency circuit provided by the related technology. Referring to Figure 1 , the radio frequency circuit (or simply referred to as the circuit) includes: a combiner 110 and an antenna 210, wherein the output end of the combiner 110 is connected to the antenna 210.

[0037] Specifically, Figure 1It is shown that the combiner 110 includes two input terminals, which are used to input signals of any single frequency band, or to input signals of two different frequency bands, such as intermediate frequency signals and high frequency signals. For example, in a CA scenario, the combiner 110 can combine the intermediate frequency signal and the high frequency signal into one path and output it to the antenna 210, and the combined signal is radiated outward by the antenna 210. Based on this circuit architecture, although the antenna routing area can be saved, the combiner 110 will cause certain losses in signal transmission. It can be known that most operators have relatively strict sensitivity indicators for the transceiver process of single-frequency band signals. When a single-frequency band signal passes through the combiner and is transmitted outward through the antenna, the sensitivity of the single-frequency band signal will decrease, and it cannot reach the sensitivity indicator defined by the Total Isotropic Sensitivity (TIS) test of the Over-the-Air (OTA) technology certification, thus affecting the user's communication experience.

[0038] Exemplarily, Figure 1 the model of the combiner 110 in it can be FLT25D2223L-4222B, which has a set frequency protection interval such as 2.25G. The closer the frequency band of the signal input to the combiner 110 is to 2.25G, the more serious the sensitivity deterioration of the signal is, and for signals of different frequency bands, the degree of sensitivity deterioration is also different. Among them, since the frequency interval between the intermediate frequency signal and the high frequency signal is relatively narrow, on the premise of ensuring the out-of-band rejection of the combiner 110 itself, the losses brought by the combiner 110 to the intermediate frequency signal and the high frequency signal are both large. Therefore, optimizing the sensitivity indicators of the intermediate frequency signal and the high frequency signal respectively has become an urgent problem to be solved.

[0039] In view of at least one of the above defects, the embodiments of the present disclosure provide a radio frequency switch module, which includes: a combiner, a first switch, and a plurality of second switches; the first switch includes a combining channel and a plurality of single-frequency band channels; the second switch includes a first signal transmission channel and a second signal transmission channel; the first signal transmission channels of the second switches are respectively connected to the single-frequency band channels of the first switch in one-to-one correspondence; the second signal transmission channels of the second switches are respectively connected to the input terminals of the combiner in one-to-one correspondence; the output terminal of the combiner is connected to the combining channel of the first switch. In this way, when the second switch switches to the first signal transmission channel, the first signal transmission channel can be connected to the corresponding single-frequency band channel, avoiding the signal transmission loss brought by the combiner, thereby improving the sensitivity of the single-frequency band signal and being beneficial to improving the user's communication experience.

[0040] Next, with reference to the accompanying drawings, the radio frequency switch module, device, and equipment provided by the embodiments of the present disclosure will be exemplarily described.

[0041] Figure 2 It is a schematic structural diagram of a radio frequency switch module provided by an embodiment of the present disclosure. Refer toFigure 2 The RF switch module includes: a combiner 110, a first switch 120, and a plurality of second switches 130; the first switch 120 includes a combining channel 121 and a plurality of single-band channels 122; the second switch 130 includes a first signal transmission channel 131 and a second signal transmission channel 132; the first switch 120 is used to control the switching between the single-band channels 122 and the combining channel 121; the second switch 130 is used to control the switching between the first signal transmission channel 131 and the second signal transmission channel 132; the first signal transmission channels 131 of the second switches 130 are respectively and correspondingly connected to the single-band channels 122 of the first switch 120; the second signal transmission channels 132 of the second switches 130 are respectively and correspondingly connected to the input ends of the combiner 110; the output end of the combiner 110 is connected to the combining channel 121 of the first switch 120.

[0042] Wherein, the first signal transmission channel 131 and the second signal transmission channel 132 are channels for transmitting signals of a preset frequency band. Exemplarily, the second switch 130 selectively switches between the first signal transmission channel 131 and the second signal transmission channel 132, so that the signals of the preset frequency band can be transmitted to the combiner 110 or the first switch 120. The channel switching can be performed according to the frequency band application requirements of the embodiments of the present disclosure, such as the CA scenario or the single-frequency application scenario, and is not limited herein.

[0043] Wherein, the combining channel 121 is a channel for connecting to the combiner 110 to transmit the combined signal of the combiner 110, which can be regarded as a multi-band signal. Exemplarily, if all the second switches 130 are switched to the second signal transmission channel 132, the combiner 110 will combine the signals of the preset frequency band transmitted from each second switch 130 into one path, and output the combined signal to the combining channel 121 of the first switch 120, so as to implement the signal transmission process in the CA scenario.

[0044] Wherein, the single-band channel 122 is a channel for connecting to the second switch 130 to transmit the signal of the preset frequency band output from the corresponding first signal transmission channel 131, which can be regarded as a single-band signal. Exemplarily, if a certain second switch 130 is switched to the first signal transmission channel 131, the single-band channel 122 of the corresponding first switch 120 will transmit the signal of the preset frequency band output therefrom, so as to implement the signal transmission process in the single-frequency application scenario. It can be seen that compared with the prior art, in which the single-band signal is transmitted outward through the combiner 110, but the signal sensitivity is reduced due to the signal transmission loss caused by the combiner 110, in the embodiments of the present disclosure, the second switch 130 is switched to the first signal transmission channel to transmit the single-band signal, without passing through the combiner 110, thus avoiding the signal transmission loss caused by the combiner 110 and greatly improving the sensitivity of the single-band signal.

[0045] Exemplarily, the number of the second switches 130 may be two, three, four or other numbers, which can be set according to the frequency band combination requirements in the CA scenario, so as to achieve carrier aggregation between more frequency bands and further improve the network throughput, which is not limited herein.

[0046] The radio frequency switch module provided by the embodiment of the present disclosure includes: a combiner 110, a first switch 120 and a plurality of second switches 130; the first switch 120 includes a combining channel 121 and a plurality of single-frequency band channels 122; the second switch 130 includes a first signal transmission channel 131 and a second signal transmission channel 132; the first switch 120 is used to control the switching between the single-frequency band channels 122 and the combining channel 121; the second switch 130 is used to control the switching between the first signal transmission channel 131 and the second signal transmission channel 132; the first signal transmission channels 131 of the second switches 130 are connected to the single-frequency band channels 122 of the first switch 120 in one-to-one correspondence; the second signal transmission channels 132 of the second switches 130 are connected to the input ends of the combiner 110 in one-to-one correspondence; the output end of the combiner 110 is connected to the combining channel 121 of the first switch 120. In this way, when the second switch 130 switches to the first signal transmission channel 131, the first signal transmission channel 131 can be connected to the corresponding single-frequency band channel 122, avoiding the signal transmission loss caused by the combiner 110, thereby improving the sensitivity of the single-frequency band signal and being beneficial to improving the communication experience of users.

[0047] In some embodiments, Figure 3 is a schematic structural diagram of another radio frequency switch module provided by the embodiment of the present disclosure. On the basis of Figure 2 , referring to Figure 3 , each second switch 130 includes a first end 133, a second end 134 and a third end 135; the first switch 120 includes a fourth end 123, a fifth end 124 and a plurality of sixth ends 125; the fifth end 124 of the first switch 120 is used to connect to an antenna; the first end 133 of the second switch 130 is used to transmit a preset frequency band signal; the second ends 134 of the second switches 130 are connected to the input ends of the combiner 110 in one-to-one correspondence, and the output end of the combiner 110 is connected to the fourth end 123 of the first switch 120; the third ends 135 of the second switches 130 are connected to the sixth ends 125 of the first switch 120 in one-to-one correspondence; the first end 133 and the second end 134 are connected to form the second signal transmission channel 132; the first end 133 and the third end 135 are connected to form the first signal transmission channel 131; the fifth end 124 and the sixth end 125 are connected to form the single-frequency band channel 122; the fifth end 124 and the fourth end 123 are connected to form the combining channel 121.

[0048] Among them, the first terminal 133, the second terminal 134, and the third terminal 135 of the second switch 130, as well as the fourth terminal 123, the fifth terminal 124, and the multiple sixth terminals 125 of the first switch 120 are all bidirectional transmission terminals, indicating that they can be used for signal input and also for signal output. It can be understood that in practical applications, by setting the above ports as bidirectional transmission terminals, not only can the signal transmission process of the RF switch module be realized, but also the signal reception process of the RF switch module can be realized.

[0049] Exemplarily, the preset frequency band signal can be a low-frequency signal, an intermediate-frequency signal, or a high-frequency signal, and in the CA scenario, the frequency bands of the signals transmitted by the first terminals 133 of different second switches 130 are different. For example, taking two second switches 130 as an example, the first terminal 133 of one second switch 130 can transmit an intermediate-frequency signal, and the first terminal 133 of the other second switch 130 can transmit a high-frequency signal, and then they are combined by the combiner 110 for external transmission. Here, the frequency band type of the preset frequency band signal is not limited.

[0050] In some embodiments, referring to Figure 3 , the first switch 120 includes a single-pole multi-throw switch.

[0051] Exemplarily, the first switch 120 can be a single-pole triple-throw switch, a single-pole quadruple-throw switch, a single-pole quintuple-throw switch, or other single-pole multi-throw switches; to reduce the application cost, a single-pole quadruple-throw switch with a higher production volume can be selected as the first switch 120, and its model can be MXD8645M, which includes three single-band channels 122 and one combined channel 121. The specific type and its model of the single-pole multi-throw switch can be set according to the number requirement of the single-band channels 122, and it is not limited here.

[0052] In some embodiments, the second switch includes a single-pole double-throw switch.

[0053] Exemplarily, the model of the single-pole double-throw switch can be HS8727, or other models of single-pole double-throw switches known to those skilled in the art, and it is not limited here.

[0054] Exemplarily, Figure 4 is a schematic structural diagram of another RF switch module provided by an embodiment of the present disclosure. Referring to Figure 4 , in the figure, the first switch 120 is shown as a single-pole quadruple-throw switch, the number of input terminals of the combiner 110 is two, the number of single-pole double-throw switches is two, and the signal transmission path of a single-band signal such as an intermediate-frequency signal is shown by the direction of the thick arrow.

[0055] For example, taking Figure 4 the orientation shown as an example, the first terminal 133 of the upper second switch 130 can be used to transmit a high-frequency signal, and the first terminal 133 of the lower second switch 130 can be used to transmit an intermediate-frequency signal.

[0056] Specifically, in a single-frequency application scenario, the lower second switch 130 switches to the first signal transmission channel. After the first end 133 of the second switch 130 receives the intermediate-frequency signal, the intermediate-frequency signal is transmitted through the first signal transmission channel to a sixth end 125 of the first switch 120, and then the intermediate-frequency signal is transmitted to other structures such as an antenna through the corresponding single-band channel 122. It should be noted that the frequency band of the intermediate-frequency signal can be Band 66, and its frequency band range is 2110 MHz to 2200 MHz. If according to Figure 1 the circuit design of the existing technology in [reference], when the intermediate-frequency signal of this frequency band passes through the combiner 110, the loss of the combiner 110 is about 2.8 db. However, according to the radio frequency switch module provided by the embodiments of the present disclosure, as Figure 4 shown, the loss of the second switch 130 is about 0.5 db, and the loss of the first switch 120 is about 0.48 db. It can be seen that the overall loss of the device is reduced by about 1.8 db, so the sensitivity of the intermediate-frequency signal of this frequency band can be increased by 1.8 db.

[0057] Similarly, in a single-frequency application scenario, the situation where the first end 133 of the upper second switch 130 transmits the high-frequency signal is the same as the above principle, and the signal transmission path can be understood by referring to it; in addition, the frequency band of the high-frequency signal can be Band40, and its frequency band range is 2300 MHz to 2400 MHz. If according to Figure 1 the circuit design of the existing technology in [reference], when the high-frequency signal of this frequency band passes through the combiner 110, the loss of the combiner 110 is about 1.9 db. However, according to the radio frequency switch module provided by the embodiments of the present disclosure, as Figure 4 shown, the loss of the second switch 130 is about 0.5 db, and the loss of the first switch 120 is about 0.48 db. It can be seen that the overall loss of the device is reduced by about 0.9 db, so the sensitivity of the high-frequency signal of this frequency band can be increased by 0.9 db.

[0058] Exemplarily, Figure 5 is a schematic structural diagram of another radio frequency switch module provided by the embodiments of the present disclosure. Referring to Figure 5 , in the figure, it is shown that the first switch 120 is a single-pole four-throw switch, the number of input ends of the combiner 110 is two, the number of single-pole double-throw switches is two, and the signal transmission paths of multi-band signals such as intermediate-frequency signals and high-frequency signals are shown by thick arrow directions.

[0059] For example, taking the orientation shown in Figure 5 as an example, the first end 133 of the upper second switch 130 can be used to transmit high-frequency signals, and the first end 133 of the lower second switch 130 can be used to transmit intermediate-frequency signals.

[0060] Specifically, in the CA scenario, both of the two second switches 130 are switched to the second signal transmission channel. After the first end 133 of the upper second switch 130 receives the high-frequency signal and the first end 133 of the lower second switch 130 receives the intermediate-frequency signal, the high-frequency signal and the intermediate-frequency signal are respectively transmitted to the combiner 110 through the second signal transmission channel, so as to combine the high-frequency signal and the intermediate-frequency signal into one path by using the combiner 110 and transmit it to other structures such as an antenna. It should be noted that although the radio frequency switch module provided in the embodiments of the present disclosure increases the losses of the second switch 130 and the first switch 120 compared with the circuit design of the prior art, such as increasing about 1 dB of loss and sacrificing the sensitivity of multi-band signals, in view of the fact that most operators have no sensitivity index requirements for multi-band signals, its influence does not need to be considered.

[0061] Combined with Figure 4 and Figure 5 , for the radio frequency switch module provided in the embodiments of the present disclosure, by switching the second switch 130 to the first signal transmission channel, the signal transmission loss caused by the combiner is avoided, thereby improving the sensitivity of single-band signals such as intermediate-frequency signals or high-frequency signals, which is beneficial to meeting the sensitivity index set by the operator.

[0062] In some embodiments, the number of input ends of the combiner is at least two.

[0063] Exemplarily, as Figure 4 , the number of input ends of the combiner 110 is two, indicating that it is a two-way combiner for combining signals of two different frequency bands. In other embodiments, the number of input ends of the combiner may also be three, four or other numbers, which are not limited herein.

[0064] In some embodiments, still referring to Figure 3 , the radio frequency switch module further includes a radio frequency transceiver chip 140; the radio frequency transceiver chip 140 is connected to the first end 133 of each second switch 130.

[0065] Among them, the radio frequency transceiver chip 140 is a chip for receiving and transmitting signals of a preset frequency band. Exemplarily, the radio frequency transceiver chip 140 can send the signals of the preset frequency band to the corresponding second switch 130. For example, in a single-frequency application scenario, the radio frequency transceiver chip 140 can send the signals of the preset frequency band to any one of the second switches 130, or in the CA scenario, the radio frequency transceiver chip 140 can send multiple signals of the preset frequency band to multiple second switches 130 one by one.

[0066] On the basis of the above embodiments, the embodiments of the present disclosure further provide an antenna device, including any one of the radio frequency switch modules provided in the above embodiments.

[0067] Exemplarily, Figure 6Schematic diagram of a structure of an antenna device provided by an embodiment of the present disclosure. Refer to Figure 6 , the antenna device further includes an antenna 210.

[0068] Among them, the number of the antennas 210 is one, and it is connected to the first switch 120. Specifically, by using one antenna 210 to connect to the first switch 120, the area of the antenna wiring is effectively saved, which is beneficial to improving the space utilization rate of the circuit design.

[0069] In some embodiments, the RF switch module includes two second switches; the two second switches are respectively used for transmitting intermediate frequency signals and high frequency signals.

[0070] Exemplarily, taking Figure 4 or Figure 5 as an example, in the CA scenario, by setting two second switches 130 to transmit intermediate frequency signals and high frequency signals respectively, the signal transmission process of the intermediate frequency signals and the high frequency signals can be realized. In this way, by using the bandwidth resources of the intermediate frequency and the high frequency simultaneously, the data transmission rate is significantly improved, and the spectrum utilization rate is increased, so that the limited spectrum resources are more fully utilized.

[0071] The embodiment of the present disclosure further provides an electronic device, including any one of the antenna devices provided by the above embodiments.

[0072] Exemplarily, the electronic device can be a communication device such as a smart phone, a tablet computer, a notebook computer, etc. For example, if the electronic device is a smart phone, due to the low cost and more types of devices in the Phase 5N architecture, it is widely used in 5G mobile phones, especially low-end 5G mobile phones. In this RF architecture, the frequency band combination of high frequency and intermediate frequency becomes a common application requirement, and optimizing the sensitivity of intermediate frequency signals or high frequency signals becomes an important means to improve network communication quality. In other embodiments, the antenna device can also be applicable to devices with Phase7 / phase7L RF architecture or other RF architectures, which is not limited here.
