伴随着科学技术的发展,通信技术得以突飞猛进的提升。无线通信技术经过长期的演化发展,当前无线通信技术中,为了提高信息传输速率,终端设备通常支持双连接的方式同时接入4G网络和5G网络。4G网络或5G网络中基站可以分别采用4G频段或5G频段与终端设备进行数据传输。

基于图1所示的应用场景,下面通过图2-图8所示的实施例,对终端设备中的通信设备的结构进行详细描述,以解决降低版图面积的技术问题。
通信设备可以包括一个或多个功率放大器芯片。每个功率放大器芯片中可以集成有至少两个功率放大器。也即是说,一个功率放大器芯片可以集成有两个功率放大器、三个功率放大器、或四个功率放大器等等,本申请实施例对此不做限定。以一个功率放大器芯片包括两个功率放大器为例,结合图2,对功率放大器芯片的内部结构进行详细描述。

在所述功率放大器芯片11中,封装壳用于封装内部器件,例如可采用标准封装工艺实现。被封装的内部器件包括但不限于如前所述的多个裸芯片、以及其他必要器件,如后续实施例提到的开关、开关组、电容或控制器等,具体可参照后续实施例的介绍。
上述PA1裸芯片所集成的功率放大器PA1和PA2裸芯片所集成的功率放大器PA2可以用于支持不同频段信号的功率放大。具体的,PA1可以支持N41频段(2496MHz–2690MHz)的功率放大;PA2可以支持B39频段(1880MHz–1920MHz)、B3频段(1710MHz–1785MHz)或者B1频段(1920MHz–1980MHz)的功率放大。
从图2中可以看出,功率放大器芯片11包括多个引脚,该多个引脚分别为:PA1的信号输入端N1,PA2的信号输入端N2,PA1的电源端V1,PA2的电源端V2,PA1和PA2的公共地端G,PA1的输出端口Po1和PA2的输出端口Po2。该多个引脚分别与外部诸如电源设备、RFIC、或天线设备等设备或器件连接,实现如图1所示的多路上行通信信号的功率放大。
本申请实施例通过将多个功率放大器裸芯片封装于同一功率放大器芯片中,可以降低功率放大器所占用的终端设备的版图的面积,有利于高度集成化的终端设备的实现。
基于图2所示的功率放大器芯片11,本申请实施例提供一种如图3所示的通信设备100,该通信设备100包括RFIC、电源设备12和功率放大器芯片11。

通过采用如图6或图8所示的通信设备,可以在保障各PA独立供电的同时,还可以降低通信设备所占用的版图面积,有利于实现高度集成化的终端设备。
请继续参考图9,其示出了本申请实施例提供的电子设备100的又一个结构示意图。 在图9中,电子设备100包括第一供电芯片121、第二供电芯片122、RFIC和功率放大器芯片11。其中,RFIC与第一供电芯片121之间的连接关系以及二者之间的信号交互、RFIC与第二供电芯片122之间的连接关系以及二者之间的信号交互可以参考图6所示的实施例中的相关描述,在此不再赘述。
功率放大器芯片11包括四个PA裸芯片,分别为PA1裸芯片、PA2裸芯片、PA3裸芯片和PA4裸芯片,其中,PA1裸芯片、PA2裸芯片、PA3裸芯片和PA4裸芯片可以分别集成有两个级联的PA。PA1裸芯片、PA2裸芯片、PA3裸芯片和PA4裸芯片的相应端通过跳线、埋线或者开关的方式分别连接至功率放大器芯片11的各引脚。功率放大器芯片11还包括电容C1、电容C2、开关K1、开关K2和开关K3。与图2-图8所示的功率放大器芯片11不同的是,本申请实施例所示的功率放大器芯片11还包括控制器CR。开关K1、开关K2和开关K3的控制端通过控制器CR控制导通或关断。除此之外,电容C1、电容C2、开关K1、开关K2和开关K3的作用、有益效果以及与其他部件之间的连接关系,与图5-图8所示的功率放大器芯片11中的相同,具体可以参考图5-图8所示的功率放大器芯片11的相关描述,在此不再赘述。控制器CR的作用以及与其他各部件之间的连接关系参见下文描述。
与图5所示的PA1裸芯片相同,PA1裸芯片用于放大第一频段(例如5G频段)的射频信号,PA1裸芯片中的前一级PA可以通过第一电源端V1连接至第一供电芯片的输出端Vcc1,PA1裸芯片中的后一级PA可以通过第二电源端V2连接至第一供电芯片的输出端Vcc2,PA1裸芯片通过信号输入端N1与RFIC的第一射频信号输出端F1连接。PA2裸芯片用于放大第二频段(例如4G中的低频频段)的射频信号,PA3裸芯片用于放大第三频段(例如4G中的中频频段)的射频信号,PA4裸芯片用于放大第四频段(例如4G中的高频频段)的射频信号。其中,PA2裸芯片、PA3裸芯片和PA4裸芯片中的前一级PA可以通过第三电源端V3均连接至第二供电芯片的输出端Vcc3,PA2裸芯片、PA3裸芯片和PA4裸芯片中的后一级PA可以通过第四电源端V4均连接至第二供电芯片的输出端Vcc4,PA2裸芯片通过信号输入端N2与RFIC的第二射频信号输出端F2连接,PA3裸芯片通过信号输入端N3与RFIC的第三射频信号输出端F3连接,PA4裸芯片通过信号输入端N4与RFIC的第四射频信号输出端F4连接。PA1裸芯片的具体工作方式参考图5所示的PA1的相关描述,PA2裸芯片、PA3裸芯片和PA4裸芯片的具体工作方式参考图5所示的PA2的相关描述,在此不再赘述。
通常,针对同一频段的信号,不同国家或地区所采用的通信频段存在细微差别。例如,针对低频频段的信号,一些地区可能采用标准38101-3-g21中频段号为LB1的频段,一些地区可能采用标准38101-3-g21中频段号为LB2的频段。基于此,为了适用多种通信频段,对于用于放大同一频段范围的信号的功率放大器(例如PA1),可以提供多个输出端口,每一个输出端口适用一种射频频段,PA裸芯片的输出端通过开关组中的开关与其中一个输出端口连接。此外,开关组还包括与输出端口一一对应连接的结点,各结点通过不同的射频信号线与各输出端口一一对应连接。其中,用于连接各结点与各输出端口的射频信号线,是基于输出端口所提供的射频频段决定的。具体的,如图9所示,PA1裸芯片后一级PA的输出端通过开关组1连接至输出端口Po1或者输出端口Po2,其中,用于连接开关组1的一个结点与输出端口Po1的射频信号线可以为适用于标准38101-3-g21中频段号为 N40的射频信号线,用于连接开关组1的另外一个节点与输出端口Po2的射频信号线可以为适用于标准38101-3-g21中频段号为N41的射频信号线;PA3裸芯片后一级PA的输出端通过开关组2连接至输出端口Po4、输出端口Po5或者输出端口Po6,其中,用于连接开关组2的第一结点与输出端口Po4的射频信号线可以为适用于标准38101-3-g21中频段号为MB39的射频信号线,用于连接开关组2的第二结点与输出端口Po5的射频信号线可以为适用于标准38101-3-g21中频段号为MB3的射频信号线,用于连接开关组2的第三结点与输出端口Po6的射频信号线可以为适用于标准38101-3-g21中频段号为MB1的射频信号线;PA4裸芯片后一级PA的输出端通过开关组3连接至输出端口Po7、输出端口Po8或者输出端口Po9,其中,用于连接开关组3的第一结点与输出端口Po7的射频信号线可以为适用于标准38101-3-g21中频段号为LB8的射频信号线,用于连接开关组3的第二结点与输出端口Po8的射频信号线可以为适用于标准38101-3-g21中频段号为LB28的射频信号线,用于连接开关组3的第三结点与输出端口Po9的射频信号线可以为适用于标准38101-3-g21中频段号为LB20的射频信号线。需要说明的是,PA1、PA3和PA4所对应的输出端的数目仅是示意性的,可以理解的是,PA1、PA3和PA4可以分别对应更多或更少的输出端,相应的,每一个开关组中可以包括更多或更少的开关。此外,如图9所示的功率放大器芯片11还包括输出端口Po3。PA2裸芯片的后一级PA的输出端通过射频信号线与输出端口Po3连接。输出端口Po3可以支持标准38101-3-g21中频段号为MHB3的射频信号。
请继续参看图9,在图9中,控制器CR通过数据输入端SDATA与RFIC的数据输出端SD连接,控制器CR通过时钟信号端SCLK与RFIC的时钟输出端SC连接,控制器CR通过电池端VBAT与外部电池连接。在功率放大器芯片11内部,控制器CR的控制端A1与PA1的增益调节端A1连接,控制器CR的控制端A11与PA1的使能端A11连接;控制器CR的控制端A2与PA2的增益调节端A2连接,控制器CR的控制端A12与PA2的使能端A12连接;控制器CR的控制端A3与PA3的增益调节端A3连接,控制器CR的控制端A13与PA3的使能端A13连接;控制器CR的控制端A4与PA4的增益调节端A4连接,控制器CR的控制端A14与PA4的使能端A14连接;控制器CR的控制端A5与第一开关组1的控制端A5连接;控制器CR的控制端A6与第二开关组2的控制端A6连接;控制器CR的控制端A7与第三开关组3的控制端A3连接;控制器CR的控制端A8与开关K1的控制端连接;控制器CR的控制端A9与开关K2的控制端连接;控制器CR的控制端A10与开关K3的控制端连接。
具体的,控制器CR可以基于时钟信号端SCLK提供的时钟周期工作。基于时钟信号端SCLK提供的时钟周期,控制器CR可以从数据输入端SDATA接收数据。该数据是RFIC通过总线发送给控制器CR的,实现工作方式控制。控制器CR可以对所接收到的数据进行解析,基于解析结果,确定出用于发射信号的功率放大器、所选用的功率放大器的增益、所选用的通信频段、和各功率放大器的供电模式(PAT供电模式或者ET供电模式)等信息。然后,基于所确定出的信息控制PA1、PA2、PA3或者PA4中的一个或多个使能,调节PA1、PA2、PA3或者PA4中的一个或多个的增益,以及控制开关组K1、开关组K3或者开关组K4的通路。以使一个或多个PA将输出端输出的信号通过天线传输至网络设备。
作为示例,假设采用PA1发射第一射频信号、采用PA3发射第二射频信号,PA1的后一级PA采用APT模式供电,PA3的后一级PA采用APT模式供电,PA1通过通信协议中的N41频段发射信号,PA3通过通信协议中的MB39频段发射信号。RFIC可以将PA1的配置信息和PA3的配置信息,通过与数据输出端SD连接的总线传输至功率放大器芯片11的数据输入端SDATA,然后通过数据输入端SDATA提供给控制器CR。控制器CR基于所接收到的数据,控制PA1和PA3使能,调节PA1和PA3的增益,将PA1的输出端连接至输出端口Po1(假设输出端口Po1支持N41频段),将PA3的输出端连接至输出端口Po4(假设输出端口Po4支持MB39频段)。此外,控制器CR还可以控制开关K1、开关K2和开关K3均导通。
上述配置信息可以承载于帧格式中传输。该帧格式可以包括用于指示功率放大器的字段、用于指示所采用的射频频段的字段和用于指示所采用的供电模式的字段等。具体场景中,还可以包括比上述帧格式所包括的字段更多或者更少的字段,根据场景的需要设置。各个字段可以通过多位比特位指示。例如,以指示PA的字段为例,可以采用四位比特位,每一位代表一个PA。例如,当采用PA1和PA3发射射频信号时,则该字段相应的比特位可以设置为“1010”。此外,控制器CR还可以控制开关K1、开关K3和开关K3均导通。
在本实施例一种可能的实现方式中,终端设备可以复用功率放大器芯片11的输出端接收下行信号,然后通过功率放大器芯片11的输出端传输至RFIC。具体的,如图10所示。在图10中,功率放大器芯片11还包括信号接收端RX1和信号接收端RX2。其中,信号接收端RX1和信号接收端RX2分别用于接收不同频率的射频信号。此外,功率放大器芯片11的输出端口Po1和输出端口Po2分别连接至RFIC的信号接收端RN1和信号接收端RN2;功率放大器芯片11内部的开关组1还包括用于将输出端口Po1与PA1的输出端连接或者与信号接收端RX1连接的开关,开关组1还包括用于将输出端口Po2与PA1的输出端连接或者与信号接收端RX2连接的开关。控制器CR的控制端A5还用于控制开关组1中的开关,使得输出端口Po2与PA1的输出端连接或者与信号接收端RX2连接。具体的,RFIC将用于指示发射信号或者接收信号的指示信息通过数据输入端SDATA发送给控制器CR,控制器CR基于解析结果控制开关组1中的各开关。
需要说明的是,如图9和图10所示的功率放大器芯片11还包括公共地端G,功率放大器芯片11内部的各地端均可以连接至公共地端G,该公共地端G可以与第一电源芯片、第二电源芯片和RFIC的公共地端连接,从而功率放大器芯片11、第一电源芯片、第二电源芯片和RFIC可以具有共同的公共电压参考信号。
本申请各实施例所示的PA适用于通信制式各种物理信道,也即是说可以对各种信道传输的信号进行功率放大。该信道可以包括但不限于:PUCCH信道、PUSCH信道、PRACH信道和SRS信道。其中,不同的信道所采用的增益可以不同。当终端设备需要发射信号(此时PA由关断状态转为使能状态)之前,或者由采用第一类型信道(如PUCCH信道)发射信号转为采用第二类型信道(如PUSCH信道)发射信号(此时PA由采用第一增益发送信号转换为采用第二增益发送信号)之前,均需要对PA进行配置(包括控制PA使能或者改变PA增益等)。其中,RFIC可以基于网络设备下发的帧格式承载的信息对PA的功率进行配置,然后将PA的配置信息传输至控制器CR,以使得控制器CR控制PA使能,以及对PA进行增益调节,以使得PA正常工作。具体场景中,终端设备中的通信装 置(例如包括基带处理器、RFIC和天线)可以监听网络设备发送的测量信息,然后对所接收到的测量信息进行解析,基于解析结果确定出与网络设备进行数据传输时用于承载数据的帧格式、各类型的数据进行传输的时间、用于进行数据传输的信道等信息。请参考图11,其示意性的示出了网络设备下发的帧格式的一个示意图。在图11中可以看出,每一帧数据可以包括两个时隙,每个时隙又可以包括14个符号。此外,承载于图11所示的帧格式中的信息还包括信号传输的起始符号,以及哪几个符号采用哪种信道进行信号传输。在图11中,示意性的示出了时隙8中的符号12开始进行信号传输。其中,时隙8中的符号12和符号13采用PUCCH信道进行信号传输;时隙9中的符号0至符号11采用PUSCH信道进行信号传输;时隙9中的符号12至符号13采用SRS信道进行信号传输。也即,时隙8中的符号12起始前,PA处于关断状态,在时隙8中的符号12开始,PA由关断状态转为使能状态。时隙9中的符号0之前,PA采用第一增益进行信号传输,时隙9中的符号0开始,PA采用第二增益进行信号传输。RFIC向控制器CR传输的PA配置信息中,还包括控制PA使能的时间以及调节PA增益的时间。通常,在距离信号开始传输之前的第一预设时间段或者在距离信道转换之前的第二预设时间段控制PA使能,或者调节PA增益。例如,在图12所示的时序中,假设T2时刻开始,PA采用第一增益进行信号传输,其对应图11所示的时隙8中的符号12起始时刻,假设T3时刻开始,PA采用第二增益进行信号传输,其对应图11所示的时隙9中的符号0起始时刻。那么,传统技术中,在T1时刻,调节PA增益以及控制PA使能,在T2时刻,调节PA增益,以使得PA采用第二进行信号传输。其中,T2减去T1的时间段t1与T3减去T2的时间段t2相同或者具有较小的差异。其通常为2us左右。由于PA由关断状态转为使能状态的过程中,具有较大的时延,且在启动过程中由于外部因素等影响,通常导致输出的信号不稳定,进而导致所传输的信号具有较高的误码率。基于此,本申请实施例中,将时间段t1与时间段t2设置不同的时间段,其中,将时间段t1的长度设置为大于时间段t2的长度,也即提前启动PA。具体的,如图13所示时序,可以在T1时刻,调节PA增益以及控制PA使能,其余各时刻与图12所示的各时刻相同。这样一来,可以使得PA具有足够的时间进入稳定的工作状态,从而可以降低误码率。此外,还可以提高首符号的误差向量幅度(EVM)。
以上所述,仅为本申请的具体实施方式,但本申请的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应以所述权利要求的保护范围为准。
