随着通信技术的发展，无线射频电路技术应用越来越广，如：无线寻呼机、手机、无线掌上电脑(Personal Digital Assistant，PDA)等，在无线射频电路技术的应用过程中，射频电路的性能指标会直接影响整个产品的质量，这些掌上产品的一个最大特点就是小型化，而小型化意味着元器件具有较高的集成性。
在射频集成电路中，为了提高不同发射支路和接收支路端口之间的隔离度，在很多应用场合需要使用信号收发控制结构。目前，信号收发控制结构一般采用以下方案：如图1所示，通过增加并联分流器shunt开关，如第一支路的发射端并联分流器TX1_shunt开关和接收端并联分流器RX1_shunt开关，提高端口之间的隔离度。但是，由于每个支路中的TXi、RXi、TXi_shunt和RXi_shunt(i＝1、2…n，n为正整数)四种开关，分别需要多个控制信号来实现该四种开关的闭合与断开，而信号收发控制结构的支路数目多，因此需要大量的控制信号来控制开关，而且每增加一个控制 开关就会占用一定的芯片面积，难以满足元器件的高集成化需求。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
实施例一
本发明实施例公开了的一种信号收发控制结构，图2为本发明实施例公开的一种信号收发控制结构的组成结构示意图，如图2所示，该信号收发控制结构包括：功率放大器210和N个控制支路220；其中，所述N个控制支路220用于根据不同的控制指令选择其中一个控制支路控制不同网络制式的第一信号的发射或第二信号的接收；所述N个控制支路220有三个端，如图4所示，图4为本发明实施例公开的一种控制支路的组成结构示意图；其中，所述N个控制支路220的第一端224分别与所述功率放大器210的输出端连接，所述N个控制支路的第二端225分别与N个外接输出端连接，所述N个控制支路220的第三端226分别与N个外接输入/输出端连接；其中，N为大于1的正整数。
这里，所述第一信号为向外界发射的信号，可称之为输出信号；第二信号为接收到外界发送过来的信号，可称之为输入信号。
所述功率放大器210，用于对输出信号进行功率放大。
这里，所述信号的网络系统包括：第二代移动通信网络，如全球移动通信(Global System for Mobile Communication，GSM)和码分多址(Code Division Multiple Access，CDMA)，其中，所述GSM包括GSM900和1800兆的数字蜂窝系统(Digital Cellular System at 1800MHz，DCS1800)；第三代移动通信网络，如宽带码分多址(Wideband Code Division Multiple Access， WCDMA)、码分多址2000(Code Division Multiple Access 2000，CDMA2000)和时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)；第四代移动通信网络，如分时长期演进(Time Division Long Term Evolution，TD-LTE)和频分双工长期演进(Frequency Division Dual Long Term Evolution，LTE FDD)等等。
这里，所述控制指令包括针对控制GSM(包括GSM900和DCS1800)、CDMA、WCDMA、CDMA2000、TD-SCDMA、LTE FDD(包括)和TD-LTE的控制指令；所述控制指令是在接收或发射某种网络制式信号时，由所述信号收发控制结构所在的电子设备产生的，从而实现从N个控制支路中选择符合该网络制式的控制支路。
具体的，所述N个控制支路包括N个输出控制开关221、N个输入控制开关222和N个辅助控制开关223；如图4所示，所述N个输出控制开关221的第一端分别与所述功率放大器210连接，所述N个输出控制开关221的第二端分别与所述N个输入控制开关222的第一端连接；所述N个输入控制开关222的第二端分别与所述N个辅助控制开关223的第一端连接；所述N个辅助控制开关223的第二端分别接地。
本发明实施例的信号收发控制结构应用于电子设备中；为了避免噪声信号的干扰，满足电子设备的无线通信质量，所述信号收发控制结构中可设置有N个滤波器230，或者N个双工器230，或者M个滤波器和K个双工器，其中，所述N为大于1的正整数，M和K为正整数，且M+K＝N。如图3所示，图3为本发明实施例公开的另一种信号收发控制结构的组成结构示意图，所述滤波器和所述双工器用于对所述第一信号和所述第二信号进行滤波处理，本发明实施例中，为了方便，在涉及到滤波器或双工器的地方均统一用滤波器；所述第一信号为发射的信号，所述第二信号为接收到的信号，该信号的网络制式包括GSM、CDMA、WCDMA、TD-SCDMA、 CDMA2000、TD-LTE和LTE FDD。
如图3所示，所述N个滤波器230分别与所述N个控制支路220的第三端一对一连接，所述信号收发控制结构还包括：N个滤波器，或N个双工器，或M个滤波器和K个双工器，用于对发射的第一信号和接收到的第二信号进行滤波处理；所述N个滤波器分别与所述N个控制支路220的第三端连接，且所述N个滤波器230的输出端分别与所述N个外接输入/输出端连接；或者，所述N个双工器分别与所述N个控制支路220的第三端连接，且所述N个双工器230的输出端分别与所述N个外接输入/输出端连接；或者，所述M个滤波器230的输入端分别与所述N个控制支路220中的M个控制支路220的第三端连接、所述M个滤波器230的输出端分别与所述N个外接输入/输出端中的M个外接输入/输出端连接，且所述K个双工器230分别与所述N个控制支路220中剩下的K个控制支路220的第三端连接、所述K个双工器230的输出端分别与所述N个外接输入/输出端中剩下的K个外接输入/输出端连接。以便于信号在发射或接收时，能够对信号进行滤波处理，滤除带外的噪声信号。
具体的，在信号收发控制结构中，由于接收或发射信号的网络制式不同，所使用的N个滤波器230的型号也不同；因此，当信号收发控制结构在进行工作时，根据不同的网络制式信号，自动选择相应的控制支路，即不同的滤波器对信号进行处理。
举例来说，假设有三个控制支路、三个滤波器，第1个控制支路连接的是滤除除GSM之外信号的滤波器，第2个控制支路连接的是滤除除WCDMA之外信号的滤波器，第3个控制支路连接的是滤除除TD-SCDMA之外信号的滤波器；那么，当接收或发射GSM信号时，系统会自动选择第1个控制支路对GSM信号进行控制和处理，而不会选择第2个和第3个控制支路；同理，当接收或发射WCDMA或是TD-SCDMA信号时，也会分 别自动选择第2个控制支路或第3个控制支路，而不会选择其它控制支路。
本发明一实施方式中，所述信号收发控制结构还包括：至少一个信号处理器240，用于处理所述第二信号，即接收到的信号，以实现模/数转换；如图3所示，所述至少一个信号处理器240的输入端分别与所述N个控制支路220的第二端连接，且所述至少一个信号处理器240的输出端分别与所述N个外接输出端连接。
本发明一实施方式中，当第i个控制支路中的第i个输出控制开关闭合ON、第i个输入控制开关断开OFF和第i个辅助控制开关ON时，所述第i个控制支路工作于发射态，用于控制所述第一信号的发射；
当所述第i个控制支路中的第i个输出控制开关OFF、第i个输入控制开关ON和第i个辅助控制开关OFF时，所述第i个控制支路工作于接收态，用于控制所述第二信号的接收；
当所述第i个控制支路中的第i个输出控制开关OFF、第i个输入控制开关ON和第i个辅助控制开关ON时，所述第i个控制支路工作于隔离态，用于控制所述第i个控制支路与第i个控制支路之外的N-1个控制支路之间的信号干扰；
其中，所述第i个控制支路为所述N个控制控制支路220中的一个；i为小于等于N的正整数
具体的，当第i个控制支路处于发射态时，由于除第i个控制支路中之外的其它控制支路的输出控制开关断开、输入控制开关闭合和辅助控制开关闭合，第i个控制支路发射的信号即便泄露到其它支路中，信号也会通过该支路的RX和RX-shunt到地，不会对其它控制支路，以及与该控制支路连接的元器件产生干扰，从而达到隔离的效果。
本发明一实施方式中，当所述第i个控制支路工作于所述发射态，且除所述第i个控制支路之外的N-1个控制支路工作于所述隔离态时，所述信号 收发控制结构用于发射所述第一信号；
当所述第i个控制支路工作于所述接收态，且除所述第i个控制支路之外的N-1个控制支路工作于所述隔离态时，所述信号收发控制结构用于接收所述第二信号。
具体的，当第1个控制支路的输出控制开关TX1闭合、输入控制开关RX1断开、辅助控制开关RX1-shunt闭合，和除第1控制支路之外的第2至第N个控制支路的输出控制开关TX断开、输入控制开关RX闭合和辅助控制开关RX-shunt闭合时，所述信号收发控制结构用于特定网络制式的信号发射；当第1个控制支路的输出控制开关TX1断开、输入控制开关RX1闭合、辅助控制开关RX1-shunt断开，和除第1控制支路之外的第2至第N个控制支路的输出控制开关TX断开、输入控制开关RX闭合和辅助控制开关RX-shunt闭合时，所述信号收发控制结构用于特定网络制式的信号接收。
通过本发明实施例的技术方案，信号收发控制结构中的每个控制支路，只使用三个控制开关便可实现控制射频信号的发射和接收，以及控制不同控制支路之间的信号干扰，这种设计，降低了控制电路的开关数目，减少了信号收发控制结构的尺寸，从而满足高度集成化的需求；此外，由于降低了控制电路的开关数目，从而也减小了寄生电容的产生，降低了输入控制开关/输出控制开关插损。
实施例二
本发明实施例还提供了一种电子设备，所述电子设备包括本发明实施例所述的信号收发控制结构。具体的，如图2所示，该信号收发控制结构包括：功率放大器210和N个控制支路220；其中，用于根据不同的控制指令控制不同网络制式的第一信号的发射或第二信号的接收；所述N个控制支路220有三个端，如图4所示，图4为本发明实施例公开的一种控制支路的组成结构示意图；其中，所述N个控制支路220的第一端224分别 与所述功率放大器210的输出端连接，所述N个控制支路的第二端225分别与N个外接输出端连接，所述N个控制支路220的第三端226分别与N个外接输入/输出端连接；其中，N为大于1的正整数。
这里，所述第一信号为向外界发射的信号，可称之为输出信号；第二信号为接收到外界发送过来的信号，可称之为输入信号。
所述功率放大器210，用于对输出信号进行功率放大。
这里，所述信号的网络系统包括：第二代移动通信网络，如GSM和CDMA，其中，所述GSM包括GSM900和DCS1800；第三代移动通信网络，如WCDMA、CDMA2000和TD-SCDMA；第四代移动通信网络，如TD-LTE和LTE FDD。
这里，所述控制指令包括针对控制GSM(包括GSM900和DCS1800)、CDMA、WCDMA、CDMA2000、TD-SCDMA、LTE FDD和TD-LTE的控制指令；所述控制指令是在接收或发射某种网络制式信号时，由所述信号收发控制结构所在的电子设备产生的，从而实现从N个控制支路中选择符合该网络制式的控制支路。
具体的，所述N个控制支路包括N个输出控制开关221、N个输入控制开关222和N个辅助控制开关223；如图4所示，所述N个输出控制开关221的第一端分别与所述功率放大器210连接，所述N个输出控制开关221的第二端分别与所述N个输入控制开关222的第一端连接；所述N个输入控制开关222的第二端分别与所述N个辅助控制开关223的第一端连接；所述N个辅助控制开关223的第二端分别接地。
为了避免噪声信号的干扰，满足电子设备的无线通信质量，所述信号收发控制结构中可设置有N个滤波器230，或者N个双工器230，或者M个滤波器和K个双工器，其中，所述N为大于1的正整数，M和K为正整数，且M+K＝N。如图3所示，图3为本发明实施例公开的另一种信号收发 控制结构的组成结构示意图，所述滤波器和所述双工器用于对所述第一信号和所述第二信号进行滤波处理，本发明实施例中，为了方便，在涉及到滤波器或双工器的地方均统一用滤波器；所述第一信号为发射的信号，所述第二信号为接收到的信号，该信号的网络制式包括GSM、CDMA、WCDMA、TD-SCDMA、CDMA2000、TD-LTE和LTE FDD。
如图3所示，所述N个滤波器230分别与所述N个控制支路220的第三端一对一连接，所述信号收发控制结构还包括：N个滤波器，或N个双工器，或M个滤波器和K个双工器，用于对发射的第一信号和接收到的第二信号进行滤波处理；所述N个滤波器分别与所述N个控制支路220的第三端连接，且所述N个滤波器230的输出端分别与所述N个外接输入/输出端连接；或者，所述N个双工器分别与所述N个控制支路220的第三端连接，且所述N个双工器230的输出端分别与所述N个外接输入/输出端连接；或者，所述M个滤波器230的输入端分别与所述N个控制支路220中的M个控制支路220的第三端连接、所述M个滤波器230的输出端分别与所述N个外接输入/输出端中的M个外接输入/输出端连接，且所述K个双工器230分别与所述N个控制支路220中剩下的K个控制支路220的第三端连接、所述K个滤波器230的输出端分别与所述N个外接输入/输出端中剩下的K个外接输入/输出端连接。以便于信号在发射或接收时，能够对信号进行滤波处理，滤除带外的噪声信号。
具体的，在信号收发控制结构中，由于接收或发射信号的网络制式不同，所使用的N个滤波器230的型号也不同；因此，当信号收发控制结构在进行工作时，根据不同的网络制式信号，自动选择相应的控制支路，即不同的滤波器对信号进行处理。
举例来说，假设有三个控制支路、三个滤波器，第1个控制支路连接的是滤除除GSM之外信号的滤波器，第2个控制支路连接的是滤除除 WCDMA之外信号的滤波器，第3个控制支路连接的是滤除除TD-SCDMA之外信号的滤波器；那么，当接收或发射GSM信号时，系统会自动选择第1个控制支路对GSM信号进行控制和处理，而不会选择第2个和第3个控制支路；同理，当接收或发射WCDMA或是TD-SCDMA信号时，也会分别自动选择第2个控制支路或第3个控制支路，而不会选择其它控制支路。
本发明一实施方式中，所述信号收发控制结构还包括：至少一个信号处理器240，用于处理所述第二信号，即接收到的信号，以实现模/数转换；如图3所示，所述至少一个信号处理器240的输入端分别与所述N个控制支路220的第二端连接，且所述至少一个信号处理器240的输出端分别与所述N个外接输出端连接。
本发明一实施方式中，当第i个控制支路中的第i个输出控制开关闭合ON、第i个输入控制开关断开OFF和第i个辅助控制开关ON时，所述第i个控制支路工作于发射态，用于控制所述第一信号的发射；
当所述第i个控制支路中的第i个输出控制开关OFF、第i个输入控制开关ON和第i个辅助控制开关OFF时，所述第i个控制支路工作于接收态，用于控制所述第二信号的接收；
当所述第i个控制支路中的第i个输出控制开关OFF、第i个输入控制开关ON和第i个辅助控制开关ON时，所述第i个控制支路工作于隔离态，用于控制所述第i个控制支路与第i个控制支路之外的N-1个控制支路之间的信号干扰；
其中，所述第i个控制支路为所述N个控制控制支路220中的一个；i为小于等于N的正整数
具体的，当第i个控制支路处于发射态时，由于除第i个控制支路中之外的其它控制支路的输出控制开关断开、输入控制开关闭合和辅助控制开关闭合，第i个控制支路发射的信号即便泄露到其它支路中，信号也会通过 该支路的RX和RX-shunt到地，不会对其它控制支路，以及与该控制支路连接的元器件产生干扰，从而达到隔离的效果。
本发明一实施方式中，当所述第i个控制支路工作于所述发射态，且除所述第i个控制支路之外的N-1个控制支路工作于所述隔离态时，所述信号收发控制结构用于发射所述第一信号；
当所述第i个控制支路工作于所述接收态，且除所述第i个控制支路之外的N-1个控制支路工作于所述隔离态时，所述信号收发控制结构用于接收所述第二信号。
具体的，当第1个控制支路的输出控制开关TX1闭合、输入控制开关RX1断开、辅助控制开关RX1-shunt闭合，和除第1控制支路之外的第2至第N个控制支路的输出控制开关TX断开、输入控制开关RX闭合和辅助控制开关RX-shunt闭合时，所述信号收发控制结构用于特定网络制式的信号发射；当第1个控制支路的输出控制开关TX1断开、输入控制开关RX1闭合、辅助控制开关RX1-shunt断开，和除第1控制支路之外的第2至第N个控制支路的输出控制开关TX断开、输入控制开关RX闭合和辅助控制开关RX-shunt闭合时，所述信号收发控制结构用于特定网络制式的信号接收。
通过本发明实施例的技术方案，信号收发控制结构中的每个控制支路，只使用三个控制开关便可实现控制射频信号的发射和接收，以及控制不同控制支路之间的信号干扰，这种设计，降低了控制电路的开关数目，减少了信号收发控制结构的尺寸，从而满足高度集成化的需求；此外，由于降低了控制电路的开关数目，从而也减小了寄生电容的产生，降低了输入控制开关/输出控制开关插损。
实施例三

步骤501：信号收发控制结构检测当前的网络制式，根据检测到的网络制式，以及所述网络制式与控制支路的对应关系确定目标控制支路。
这里，所述控制支路有N个，所述目标控制支路为N个控制支路中的一个；N为大于1的正整数。
这里，所述信号收发控制结构包括：功率放大器、N个控制支路、至少一个信号处理器，以及N个滤波器、或N个双工器、或M个滤波器和K个双工器(M+K＝N)。在所述信号收发控制结构应用到电子设备之前，设置网络制式与控制支路的对应关系。
这里，所述目标网络制式包括但不限于：第二代移动通信网络，如GSM和CDMA，其中，所述GSM包括GSM900和DCS1800；第三代移动通信网络，如WCDMA、CDMA2000和TD-SCDMA；第四代移动通信网络，如TD-LTE和LTE FDD。

本发明一实施方式中，当所述目标控制支路中的输出控制开关闭合ON、输入控制开关断开OFF和辅助控制开关ON时，所述目标控制支路工作于发射态，用于控制所述第一信号的发射。
本发明一实施方式中，当所述目标控制支路中的输出控制开关OFF、输入控制开关ON和辅助控制开关OFF时，所述目标控制支路工作于接收态，用于控制所述第二信号的接收。

步骤502：信号收发控制结构根据接收到的控制指令控制所述目标控制支路执行第一信号的发射或第二信号的接收。
这里，所述第一信号为向外界发射的信号，可称之为输出信号；第二信号为接收到外界发送过来的信号，可称之为输入信号。
具体地，假设所述目标控制支路控制的是GSM网络信号，信号收发控制结构根据接收到的控制指令控制所述目标控制支路执行所述GSM网络的第一信号发射，或控制所述目标控制支路执行所述GSM网络的第二信号的接收。
本发明一实施方式中，当所述目标控制支路工作于发射态，且除所述目标控制支路之外的N-1个控制支路工作于隔离态时，所述信号收发控制结构输出所述第一信号。
本发明一实施方式中，当所述目标控制支路工作于接收态，且除所述目标控制支路之外的N-1个控制支路工作于所述隔离态时，所述信号收发控制结构输入所述第二信号。
本发明一实施方式中，所述控制所述目标控制支路执行第一信号的发射之前，所述方法还包括：所述信号收发控制结构中的滤波器或双工器对所述第一信号进行滤波处理，滤除所述第一信号之外的噪声信号；
所述控制所述目标控制支路执行第二信号的接收之后，所述方法还包括：所述信号收发控制结构中的滤波器或双工器对所述第二信号进行滤波处理，滤除所述第二信号之外的噪声信号；
本发明一实施方式中，所述信号收发控制结构中的信号处理器对滤除所述噪声信号后的所述第二信号进行模/数转换处理。
通过本发明实施例的技术方案，一方面，实现了根据信号的网络制式 选择相应的控制支路控制射频信号的发射和接收，以及控制不同控制支路之间的信号干扰；另一方面，相对于图1所示的现有技术，由于减少了控制电路的开关数目，从而降低了信号的插入损耗。
此外，本发明实施例的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该软件产品存储在一个存储介质中，包括若干指令用以使得一台移动设备执行本发明各个实施例所述方法的全部或部分。而前述的存储介质包括闪存等各种可以存储程序代码的介质。这样，本发明实施例不限制于任何特定的硬件和软件结合。
相应地，本发明实施例还提供一种存储介质，其中存储有程序，该程序配置为执行本发明实施例的信号收发控制方法。
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。凡在本发明的精神和范围之内所作的任何修改、等同替换和改进等，均包含在本发明的保护范围之内。
