本公开涉及移动通信技术领域，特别涉及一种射频前端电路及电子设备。
背景技术
随着5G技术发展，5G终端的射频前端设计比4G更要复杂，尤其是NSA(Non-Standalone：非独立组网)模式下有很多ENDC(E-UTRA-NR Dual Connectivity：LTE和NR的双连通)组合，现有的组合设计中需要使用多个PA(PowerAmplifier：功率放大器)或者PAMID(PA+Duplexer+Filter+ASM：集成双工器的功放模块)来实现不同的ENDC组合，例如在同时实现如下ENDC组合时需要3颗PA，三个功率放大器支持三种LTE和NR双连接模式分别为LTE B3&NR N3、LTE B3&NRN7和LTE B28&NR N2，所有的ENDC组合必须遵循具有两种不同链路分别进行信号传输的模式，为了适应多种ENDC组合，那么就要求功率放大器能够接收两种不同链路发射的输入信号，以便于在ENDC组合时可以任意选择其中一种链路接收输入信号完成ENDC组合；但是现有的射频前端电路中的功率放大器的输入信号来自于同一个发射链路，使得ENDC组合受到限制。
因而现有技术还有待改进和提高。

下面结合附图，通过对实施例的描述，对发明内容作进一步说明。
请参阅图1，本公开提供的一种射频前端电路包括收发器100、功率放大器200、第一发射链路、第二发射链路和第一总线；所述收发器100与所述功率放大器200电性连接；其中，所述第一发射链路用于将所述收发器100发送的低频段信号传输至所述功率放大器200；所述第二发射链路用于将所述收发器100发送的中频段信号和高频段信号传输至所述功率放大器200；所述第一总线用于将所述收发器100发送的第一控制信号传输至所述功率放大器200；本公开通过设置两个发射链路以及一个独立的传输总线，确保功率放大器200在ENDC组合时不受限制，能够实现与其他功率放大器200的任意组合，进而解决现有的射频前端电路ENDC组合受限制的问题。
具体地，当所述射频前端电路参与信号发射时，若需要发射低频段信号，所述收发器100通过所述第一发射链路发送低频段信号至所述功率放大器200，由所述功率放大器200将所述低频段信号放大后进行输出，以便于后续发射所述低频段信号；若需要发射所述中频段信号和所述高频段信号，则所述收发器100通过所述第二链路发送所述中频段信号和所述高频段信号至所述功率放大器200，进而由所述功率放大器200将所述中频信号和所述高频信号放大后输出，以便于后续发射所述中频信号和所述高频信号，由此使得所述功率放大器200可以交替工作在第一发射链路和所述第二发射链路。本实施例中，所述功率放大器200为MMPA(Multimode multifrequency PA：多模多频功率放大器200)；其中，所述功率放大器200的工作由所述收发器100进行控制，也就是说收发器100会输出相关的控制信号控制功率放大器200的工作，确保所述功率放大器200能够正常稳定地工作。而为了避免所述功率放大器200在进行ENDC组合时，不占用其他功率放大器200的传输总线，因此本公开中在所述功率放大器200和所述收发器100之间独立设置了一条传输总线即所述第一总线，那么就由所述收发器100通过所述第一总线向所述功率放大器200传输第一控制信号，第一控制信号为所述功率放大器200工作需要的相关控制指令，通过为所述功率放大器200单独设置一条传输总线，能够有效避所述功率放大器200在进行ENDC 组合使用时与其他功率放大器的传输总线发生冲突；本公开通过设置两个发射链路以及一个独立的传输总线，确保功率放大器200在ENDC组合时不受限制，能够实现与其他功率放大器的任意组合，进而解决现有的射频前端电路ENDC组合受限制的问题。
进一步地，所述射频前端电路还包括第一功放模块300、第二功放模块400、第二总线和第三总线，所述第一功放模块300和所述第二功放模块400分别与所述收发器100连接，本实施例中所述功率放大器200、所述第一功放模块300和所述第二功放模块400均分别与所述收发器100电性连接。本实施例中所述第一功放模块300和所述第二功放模块400均包括PAMID(PA+Duplexer+Filter+ASM：集成双工器的功放模块)，记所述第一功放模块300为PAMID1，所述第二功放模块400为PAMID2；其中，所述功率放大器200、所述第一功放模块300和所述第二功放模块400两两之间组合可实现ENDC模式；所述第二总线用于将所述收发器100发送的第二控制信号传输至所述第一功放模块300；所述第三总线用于将所述收发器100发送的第三控制信号传输至所述第二功放模块400；所述第一功放模块300、所述第二功放模块400和所述功率放大器200均各自有一路总线与所述收发器100连接，在实现ENDC模式时，所述收发器100可通过各自的总线向所述第一功放模块300、所述第二功放模块400和功率放大器200传输控制信号，确保功放模块以及功率放大器200能够正常的工作。
其中，所述功率放大器200、所述第一功放模块300和所述第二功放模块400的工作由所述收发器100进行控制，当所述收发器100需要控制所述第一功放模块300工作时，由所述收发器100通过所述第二总线向所述第一功放模块300传输第二控制信号，控制所述第一功放模块300进入相应的工作状态；当所述收发器100需要控制所述第二功放模块400工作时，由所述收发器100通过所述第三总线向所述第二功放模块400传输第三控制信号，控制所述第二功放模块400进行相应的工作状态；当所述收发器100需要控制功率放大器200工作时，则由所述收发器100通过所述第一总线向所述功率放大器200传输第一控制信号，通过设置三路独立的总线，不论所述功率放大器200与哪一个功放组合实现ENDC模式，所述功率放大器200均不会和另外一个功放共用总线，由此有效避所述功率放大器200在进行ENDC组合使用时与其他功率放大器200的传输总线发生冲突；本公开 通过设置两个发射链路以及一个独立的传输总线，确保功率放大器200在ENDC组合时不受限制，能够实现与其他功率放大器200的任意组合，进而解决现有的射频前端电路ENDC组合受限制的问题，确保所述功率放大器200能够正常稳定地工作。
进一步地，所述第一发射链路还用于将所述收发器100发送的高频段信号传输至所述第一功放模块300；所述第二发射链路还用于将所述收发器100发送的低频段信号传输至所述第二功放模块400；当所述射频前端电路参与信号发射时，所述收发器100向所述第一功放模块300发射信号时，则是通过所述第一发射链路向所述第一功放模块300发射所述高频段信号，之后由所述第一功放模块300将所述高频段信号进行放大后输出，以便于后续进行发射；所述收发器100向所述第二功放模块400发射信号时，则是通过所述第二发射链路向所述第二功放模块400发射低频段信号，之后由所述第二功放模块400将所述低频段信号进行放大后输出，以便于后续进行发射，由此根据不同频段的信号选择不同的发射链路进行发射，避免了功放模块的输入信号来自同一个发射链路。
