In a preferred implementation, the radio frequency front end device may include, but is not limited to, at least one of the following:
PA类器件、 开关类产品、 天线调谐产品、 LNA产品。 优选地，在步骤 S202中，根据相同的射频前端器件的数量获取增加的管脚的数量 可以包括以下操作步骤： 步骤 S1 : 确定在每个射频前端器件中的标识元件所包含的比特位的数量； 步骤 S2: 采用如下公式计算增加的管脚的数量： X=2Y， 其中， Υ为增加的管脚的 数量， X为相同的射频前端器件的数量， 并且 Χ≤2Ν， Ν为标识元件所包含的比特位的 数量， X、 Υ、 Ν均为正整数。 在优选实施例中， 上述管脚可以为 ID_SEL管脚， 对于 ID_SEL管脚的设计， 可 以考虑此类器件同时使用多个器件的概率， 1个 ID_SEL管脚可以同时支持 2个相同的 器件同时工作， 2个 ID_SEL管脚可以支持 4个相同的器件同时工作， 以此类推， Y个 ID_SEL管脚可以同时支持 2Y个相同的器件同时工作。 但是， 同时工作的相同器件的 数量并不可以无限制地增加， 其需要受到射频前端器件的标识（例如： USID)元件所 包含的比特位的数量的限制。假设 USID元件有 4个 bit位， 那么同时工作的相同器件 的数量最多为 24个， 即 16个。 在优选实施例中， PA类器件优选最多可以设置 2个 ID_SEL管脚， 开关类产品优 选最多可以支持 2个 ID_SEL管脚， 天线调谐产品优选最多可以设置 1个 ID_SEL管 脚， LNA产品优选最多可以设置 1个 ID_SEL管脚。 优选地，在步骤 S204中，采用增加的管脚对射频前端控制接口进行复用可以包括 以下步骤： 步骤 S3: 获取增加的管脚与标识元件所包含的比特位中的待连接的比特位的连接 关系信息以及待连接的比特位中每个比特位所表示的状态信息； 步骤 S4: 按照连接关系信息和状态信息对射频前端控制接口进行复用。 在优选实施例中， 需要获知在射频前端器件中添加的一个或多个管脚与该射频前 端器件的标识元件所包含的比特位中的部分或者全部比特位相互之间的连接关系； 同 时还需要获知与每个比特位相连接的管脚采用了何种处理方式 （悬空或者接地） 从而 确定每个比特位所表示的状态信息。 通过获取到的连接关系信息以及状态信息可以对 当前同时工作的相同的射频前端器件加以区分， 对射频前端控制接口进行复用。 优选地， 在步骤 S3中， 获取连接关系信息可以包括以下操作： 步骤 S31 : 根据增加的管脚的数量确定待连接的比特位的数量； 步骤 S32: 在待连接的比特位中查找最低比特位； 步骤 S33: 从最低比特位开始将增加的每个管脚与待连接的每个比特位进行连接， 其中， 增加的每个管脚与待连接的每个比特位为一一映射关系。 在优选实施例中， 通过当前同时工作的相同的射频前端器件的数量可以计算出每 个射频前端器件所需添加管脚的数量。 其次， 通过所需添加管脚的数量又可以进一步 确定所需连接的比特位的数量。 然后， 可以在标识元件中查找到最低比特位依次进行 连接， 每个管脚与每个比特位一一对应。 例如： 当前同时工作的完全相同的射频前端器件有 4个， 按照相关技术中所采用 的技术方案， 4个完全相同的射频前端器件需要各自与一组 RFFE 接口相连接， 即需 要 RFFE1、 RFFE2、 RFFE3和 RFFE4。 而采用本发明所提供的技术方案， 假设射频前 端器件的标识元件有 4个 bit位，根据上面分析得到的结论可知，若想实现 4个完全相 同的射频前端器件复用， 则需要在每个射频前端器件上增加 2个管脚 （例如： 管脚 1 和管脚 2)， 而根据需要添加 2个管脚又可以进一步确定需要使用标识元件其中的 2个 bit位。 在该实例中， 可以选取最低比特位 （第 Obit位） 和次低比特位 （第 lbit位）， 其连接方式为 2个管脚与 2个 bit位进行一一对应的连接， 既可以采用将管脚 1与第 Obit位连接、 管脚 2与第 lbit位连接； 也可以采用将管脚 1与第 lbit位连接、 管脚 2 与第 Obit位连接。 然后采用对上述 2个管脚进行悬空或者接地处理以区分 4个完全相 同的射频前端器件， 以将管脚 1与第 Obit位连接、 管脚 2与第 lbit位连接为例， 具体 如下： PA devices, switch products, antenna tuning products, LNA products. Preferably, in step S202, obtaining the number of increased pins according to the number of the same radio frequency front end device may include the following steps: Step S1: determining the number of bits included in the identification component in each radio frequency front end device Step S2: Calculate the number of added pins using the following formula: X=2 Y , where Υ is the number of added pins, X is the number of identical RF front-end devices, and Χ ≤ 2 Ν , Ν is the identification The number of bits contained in the component, X, Υ, Ν are positive integers. In a preferred embodiment, the above pin can be an ID_SEL pin. For the design of the ID_SEL pin, the probability of using multiple devices simultaneously can be considered. One ID_SEL pin can simultaneously support two identical devices simultaneously. Two ID_SEL pins can support four identical devices working at the same time, and so on, Y ID_SEL pins can simultaneously support 2 Y identical devices to work simultaneously. However, the number of identical devices operating at the same time cannot be increased without limitation, and it needs to be limited by the number of bits contained in the identification (e.g., USID) component of the RF front-end device. Suppose USID element has four bit bits, then the number of the same device while working up to 2 4, i.e., 16. In a preferred embodiment, the PA type device preferably has up to two ID_SEL pins, the switch type product preferably supports up to two ID_SEL pins, and the antenna tuning product preferably can have up to one ID_SEL pin, and the LNA product preferably can be at most Set 1 ID_SEL pin. Preferably, in step S204, multiplexing the radio frequency front end control interface by using the added pin may include the following steps: Step S3: acquiring the bit to be connected in the bit included in the added pin and the identification component. The connection relationship information and the status information represented by each bit in the bit to be connected; Step S4: multiplexing the radio frequency front end control interface according to the connection relationship information and the status information. In a preferred embodiment, it is necessary to know the connection relationship between one or more pins added in the RF front end device and some or all of the bits included in the identification elements of the RF front end device; It is necessary to know what processing method (floating or grounding) is used for the pin connected to each bit to determine the status information represented by each bit. Through the obtained connection relationship information and status information, the same RF front-end devices that are currently working simultaneously can be distinguished, and the RF front-end control interface is multiplexed. Preferably, in step S3, obtaining the connection relationship information may include the following operations: Step S31: determining the number of bits to be connected according to the number of added pins; Step S32: Finding the lowest bit among the bits to be connected Step S33: Connect each of the added pins to each bit to be connected from the lowest bit, wherein each of the added pins has a one-to-one mapping relationship with each bit to be connected. In a preferred embodiment, the number of add pins required for each RF front end device can be calculated by the number of identical RF front end devices currently operating simultaneously. Second, the number of bits required to be connected can be further determined by the number of pins required to be added. Then, the lowest bit can be found in the identification component to be sequentially connected, and each pin has a one-to-one correspondence with each bit. For example, there are four identical RF front-end devices that work simultaneously. According to the technical solution adopted in the related art, four identical RF front-end devices need to be connected to a group of RFFE interfaces, that is, RFFE1 and RFFE2 are required. RFFE3 and RFFE4. According to the technical solution provided by the present invention, it is assumed that the identification component of the RF front-end device has 4 bit bits. According to the conclusions obtained by the above analysis, if four identical RF front-end device multiplexing are to be realized, Add 2 pins to the RF front-end device (for example: pin 1 and pin 2), and add 2 pins as needed to further determine which of the 2 bits need to be used. In this example, the lowest bit (the 0th bit) and the second low bit (the 1st bit) can be selected, and the connection mode is a one-to-one connection between the two pins and the two bit bits, which can be adopted. Pin 1 is connected to the 0th bit, and pin 2 is connected to the 1st bit. It is also possible to connect pin 1 to the 1st bit and pin 2 to the 0th bit. Then, the above two pins are suspended or grounded to distinguish four identical RF front-end devices, and the pin 1 is connected to the Obit bit, and the pin 2 is connected to the 1st bit as an example, as follows:
( 1 ) 第 1个射频前端器件： 对管脚 1和管脚 2均进行接地处理， 因此， 第 Obit 位和第 lbit位均为低电平， 即 00； (2) 第 2个射频前端器件： 对管脚 1进行悬空处理， 而对管脚 2进行接地处理， 因此， 第 Obit位为高电平， 而第 lbit位为低电平， 即 01 ; (1) The first RF front-end device: Grounding both pin 1 and pin 2, therefore, the 0th bit and the 1st bit are both low, ie 00; (2) The second RF front-end device: The pin 1 is suspended, and the pin 2 is grounded. Therefore, the 0th bit is high, and the 1st bit is low, ie 01;
(3 ) 第 3个射频前端器件： 对管脚 1进行接地处理， 而对管脚 2进行悬空处理， 因此， 第 Obit位为低电平， 而第 lbit位为高电平， 即 10; (4) 第 4个射频前端器件： 对管脚 1和管脚 2均进行悬空处理， 因此， 第 Obit 位和第 lbit位均为高电平， 即 11。 优选地， 在步骤 S3中， 获取状态信息可以包括以下处理方式之一： 方式一、 对每个比特位所连接的管脚进行悬空处理， 获取该比特位所表示的第一 状态； 方式二、 对每个比特位所连接的管脚进行接地处理， 获取该比特位所表示的第二 状态。 在优选实施例中， 图 3是根据本发明优选实施例的相同器件的 ID_SEL管脚设计 方法的示意图。 如图 3所示， 假设在射频前端器件上添加了 1个 ID_SEL管脚， 其内 部既可以通过上拉的方式将该管脚上拉至高电平， 使其默认状态设置为高， 即与该 ID_SEL管脚连接的 bit位默认设置为 1 ; 也可以通过接地的方式将该管脚变换至低电 平， 使其默认状态设置为低， 即与该 ID_SEL管脚连接的 bit位默认设置为 0。 当需要 使用两个完全相同的器件时， 第一个器件的 ID_SEL管脚可以悬空， 保持其状态为高； 而第二个器件的 ID_SEL管脚可接地， 保持其状态为低。 由此两个器件的 USID 元件 的其中一个 bit位就分别为 1和 0， 即可在同一组 RFFE接口上加以区分。 图 4是根据本发明实施例的射频前端器件的结构示意图。 如图 4所示， 该射频前 端器件可以包括： Y个管脚 10;每个管脚 10，均设置为对射频前端控制接口进行复用， 其中， Y是根据在射频前端控制接口上待连接的相同的射频前端器件的数量计算得到 的， Y为正整数。 采用如图 4所示的器件， 解决了相关技术中在射频前端器件相同的情况下每个射 频前端器件需要分别使用一组射频前端控制接口的问题， 进而可以节省在多模多频段 移动终端的射频前端电路设计过程中所使用的 RFFE接口，提高移动终端 PCB的设计 空间和尺寸利用率， 降低电路设计的复杂度。 优选地， 如图 5所示， 上述器件还可以包括： 标识元件； 标识元件 20， 与 Y个管 脚 10相连接， 设置为在采用 Y个管脚对射频前端控制接口进行复用之后， 对相同的 射频前端器件进行区分。 优选地， 采用如下公式计算管脚的数量： X=2Y， 其中， X为相同的射频前端器件 的数量， 并且 Χ≤2Ν， Ν为标识元件所包含的比特位的数量， X、 Ν均为正整数。 优选地， 每个管脚 10， 均设置为与标识元件中的一个比特位相连接， 其中， 每个 管脚所连接的比特位互异。 优选地， 每个管脚 10， 均设置为在进行悬空处理后， 与该管脚相连接的比特位表 示为第一状态； 在进行接地处理后， 与该管脚相连接的比特位表示为第二状态。 下面结合图 6至图 7所示优选实施方式对上述优选过程作进一步的描述。 图 6是根据本发明优选实施例的使用一组 RFFE接口控制射频前端器件的连接示 意图。 如图 6所示， 在 RFFE射频前端电路设计的方案中， 全部 RFFE射频前端器件 均连接在一组 RFFE接口上， 对于完全相同 （同厂商同规格型号） 的器件而言， 可以 通过 ID_SEL管脚的不同设计方法加以区分， 以此实现完全相同的 MIPI RFFE器件在 一组 RFFE接口同时工作的方案。在该优选实施例中，通过在 RFFE接口上添加 ID_SEL 管脚的方式，即可实现相同器件使用一组 RFFE接口。对于主集的 LNA而言，其 ID_SEL 管脚可以采用悬空的设计， 使其 USID被设置为默认值（高电平）， 而对于分集的 LNA 而言， 其 ID_SEL管脚可以采用接地的设计， 保持该管脚为低电平， 进而使其 USID 与主集相区分，这样就可以区分出两颗相同的 LNA。采用此方案，可以节省一组 RFFE 接口， 提高终端 PCB设计空间和尺寸利用率， 降低电路设计成本复杂度。 图 7是根据本发明优选实施例的前端器件的 USID设计方法示意图。如图 7所示， 在射频前端器件中可以添加一个或两个管脚 （即 ID_SEL)， 如果设计为两个管脚， 则 可分别称之为 ID_SEL0和 ID_SEL1。使该管脚与 USID寄存器的低 bit位（BitO )相连 接， 同时， 这两个管脚在器件内部进行上拉处理。 当该管脚悬空时， 由于内部已经进 行了上拉处理， 呈现高电平状态， 此时， 可以设置高电平为器件 USID 的默认值。 当 该管脚接地时， 呈现低电平状态， 此时， 器件 USID的低 bit位被标识为 0， 与 USID 的默认值不同。 通过该优选实施例， 可以实现两个相同的器件具有不同的 USID。 需要说明的是， 为了增加本发明的实用性， 射频前端器件中 ID_SEL管脚的添加 可以考虑器件重复使用的概率以及 RFFE接口规范对 USID的考虑。 例如： 对 PA和 LNA这类器件可以预留 2个 ID SEL管脚， 对于天线开关和天线调谐模块这类器件可 以预留 1个 ID_SEL管脚。 如果添加 2个管脚， 则可以实现在同一射频方案中同时使 用四个完全相同的器件。 如果添加 1个管脚， 则可以实现在同一射频方案中同时使用 两个完全相同的器件。 图 8是根据本发明实施例的射频前端控制接口的复用装置的结构框图。 如图 8所 示， 该射频前端控制接口的复用装置可以包括： 获取模块 10， 设置为根据在射频前端 控制接口上待连接的相同的射频前端器件的数量获取在每个射频前端器件中增加的管 脚的数量； 复用模块 20， 设置为采用增加的管脚对射频前端控制接口进行复用。 优选地， 如图 9所示， 获取模块 10可以包括： 确定单元 100， 设置为确定在每个 射频前端器件中的标识元件所包含的比特位的数量； 计算单元 102， 设置为采用如下 公式计算增加的管脚的数量： X=2Y， 其中， Υ为增加的管脚的数量， X为相同的射频 前端器件的数量， 并且 Χ≤2Ν， Ν为标识元件所包含的比特位的数量， X、 Υ、 Ν均为 正整数。 优选地， 如图 9所示， 复用模块 20可以包括： 获取单元 200， 设置为获取增加的 管脚与标识元件所包含的比特位中的待连接的比特位的连接关系信息以及待连接的比 特位中每个比特位所表示的状态信息； 复用单元 202， 设置为按照连接关系信息和状 态信息对射频前端控制接口进行复用。 优选地， 获取单元 200可以包括： 确定子单元（图中未示出）， 设置为根据增加的 管脚的数量确定待连接的比特位的数量； 查找子单元（图中未示出）， 设置为在待连接 的比特位中查找最低比特位； 连接子单元（图中未示出）， 从最低比特位开始将增加的 每个管脚与待连接的每个比特位进行连接， 其中， 增加的每个管脚与待连接的每个比 特位为一一映射关系。 优选地， 获取单元 200还可以包括： 第一获取子单元（图中未示出）， 设置为对每 个比特位所连接的管脚进行悬空处理， 获取该比特位所表示的第一状态； 第二获取子 单元（图中未示出）， 设置为对每个比特位所连接的管脚进行接地处理， 获取该比特位 所表示的第二状态。 从以上的描述中， 可以看出， 上述实施例实现了如下技术效果 （需要说明的是这 些效果是某些优选实施例可以达到的效果）：通过本发明提供的能够同时使用多个完全 相同的 MIPI RFFE接口器件的射频前端控制方案可以在射频前端存在两个或者两个以 上同一厂商同一型号的器件的情况下， 仍然可以使用一组 RFFE接口来实现对所有前 端器件的控制。 工业实用性 如上所述， 本发明实施例提供的一种射频前端器件以及射频前端控制接口的复用 方法具有以下有益效果： 可以节省在多模多频段移动终端的射频前端电路设计过程中 所使用的 RFFE接口， 提高移动终端 PCB的设计空间和尺寸利用率， 降低电路设计的 复杂度。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布在多个计算装置所 组成的网络上， 可选地， 它们可以用计算装置可执行的程序代码来实现， 从而， 可以 将它们存储在存储装置中由计算装置来执行， 并且在某些情况下， 可以以不同于此处 的顺序执行所示出或描述的步骤， 或者将它们分别制作成各个集成电路模块， 或者将 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样， 本发明不限制于任 何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领域的技 术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内， 所作的 任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。 (3) The third RF front-end device: Grounding the pin 1 and floating the pin 2, therefore, the 0th bit is low and the 1st bit is high, ie 10; 4) The fourth RF front-end device: Both pin 1 and pin 2 are left floating. Therefore, the Obit bit and the 1st bit are both high, that is, 11. Preferably, in step S3, the obtaining status information may include one of the following processing manners: Method 1: performing a dangling process on a pin connected to each bit to obtain a first state represented by the bit; The pin connected to each bit is grounded to obtain the second state represented by the bit. In a preferred embodiment, FIG. 3 is a schematic illustration of an ID_SEL pin design method for the same device in accordance with a preferred embodiment of the present invention. As shown in Figure 3, it is assumed that one ID_SEL pin is added to the RF front-end device, and the internal pull-up can be pulled up to the high level, so that the default state is set to high, that is, The bit of the ID_SEL pin is set to 1 by default; the pin can also be changed to a low level by grounding, and its default state is set to low, that is, the bit connected to the ID_SEL pin is set to 0 by default. . When two identical devices are required, the ID_SEL pin of the first device can be left floating to keep its state high; while the ID_SEL pin of the second device can be grounded, keeping its state low. Thus, one of the bits of the USID component of the two devices is 1 and 0, respectively, and can be distinguished on the same set of RFFE interfaces. 4 is a schematic structural diagram of a radio frequency front end device according to an embodiment of the present invention. As shown in FIG. 4, the RF front-end device may include: Y pins 10; each pin 10 is configured to multiplex the RF front-end control interface, where Y is to be connected according to the RF front-end control interface. The number of identical RF front-end devices is calculated, and Y is a positive integer. The device shown in FIG. 4 solves the problem that each RF front-end device needs to use a set of RF front-end control interfaces in the same case of the RF front-end device in the related art, thereby saving the multi-mode multi-band mobile terminal. The RFFE interface used in the RF front-end circuit design process improves the design space and size utilization of the mobile terminal PCB and reduces the complexity of the circuit design. Preferably, as shown in FIG. 5, the device may further include: an identification component; the identification component 20 is connected to the Y pins 10, and is configured to use the Y pins to multiplex the RF front-end control interface, The same RF front-end device is distinguished. Preferably, the number of pins is calculated by the following formula: X = 2 Y , where X is the number of identical RF front-end devices, and Χ ≤ 2 Ν , Ν is the number of bits contained in the identification component, X, Ν Both are positive integers. Preferably, each of the pins 10 is disposed to be connected to one of the identification elements, wherein the bits connected to each of the pins are different. Preferably, each pin 10 is arranged to be connected to the pin after the dangling process, and the bit connected to the pin is represented as a first state; after the grounding process is performed, the bit connected to the pin is expressed as Second state. The above preferred process will be further described below in conjunction with the preferred embodiment illustrated in Figures 6-7. 6 is a schematic diagram of the connection of a radio frequency front end device using a set of RFFE interfaces in accordance with a preferred embodiment of the present invention. As shown in Figure 6, in the RFFE RF front-end circuit design, all RFFE RF front-end devices are connected to a set of RFFE interfaces. For the same device (same model and model), the ID_SEL pin can be used. The different design methods are differentiated to achieve the same scenario where the same MIPI RFFE device operates simultaneously on a set of RFFE interfaces. In the preferred embodiment, the same device is used to implement a set of RFFE interfaces by adding ID_SEL pins to the RFFE interface. For the LNA of the main set, its ID_SEL pin can be left floating, so that its USID is set to the default value (high level), and for the diversity LNA, its ID_SEL pin can be grounded. Keep this pin low, which distinguishes its USID from the main set so that two identical LNAs can be distinguished. With this solution, a set of RFFE interfaces can be saved, the terminal PCB design space and size utilization can be improved, and the circuit design cost complexity can be reduced. 7 is a schematic diagram of a USID design method for a front end device in accordance with a preferred embodiment of the present invention. As shown in Figure 7, one or two pins (ie, ID_SEL) can be added to the RF front-end device. If designed as two pins, they can be called ID_SEL0 and ID_SEL1, respectively. This pin is connected to the low bit (BitO) of the USID register, and the two pins are pulled up inside the device. When the pin is left floating, since the internal pull-up process has been performed, it assumes a high state. At this time, the high level can be set to the default value of the device USID. When the pin is grounded, it assumes a low state. At this time, the low bit of the USID of the device is identified as 0, which is different from the default value of the USID. With this preferred embodiment, it is possible to achieve that two identical devices have different USIDs. It should be noted that, in order to increase the utility of the present invention, the addition of the ID_SEL pin in the RF front-end device may take into account the probability of device reuse and the consideration of the USID by the RFFE interface specification. For example: Two ID SEL pins can be reserved for devices such as PA and LNA, for devices such as antenna switches and antenna tuning modules. To reserve 1 ID_SEL pin. If you add 2 pins, you can use four identical devices simultaneously in the same RF solution. If you add 1 pin, you can use two identical devices simultaneously in the same RF solution.
