下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
图1为本申请实施例提供的一种功率控制装置的示意图，功率控制装置1包括多个功率放大支路，多个功率放大支路包括功率放大支路11、功率放大支路12、…、功率放大支路1n，n为大于2的正整数；其中，功率放大支路11包括驱动器件11-1、级间匹配电路11-2和功率放大器11-3；功率放大支路12包括驱动器件12-1、级间匹配电路12-2和功率放大器12-3；功率放大支路1n包括驱动器件1n-1、级间匹配电路1n-2和功率放大器1n-3；其中，每个级间匹配电路用于调节同一功率放大支路内的驱动器件的输出阻抗和同一功率放大支路内的功率放大器的输入阻抗。
随着移动通信技术的发展，通讯系统采用的信号带宽的范围越来越宽，使用的频率范围也越来越宽，然而，每个功率放大支路的放大增益有限，只能对有限频段内的频率信号进行处理，为了实现功率控制装置1支持多种网络制式和多个频段，将支持不同频段下的频率信号的多个功率放大支 路集成，得到功率控制装置1；其中，多种网络制式包括码分多址(CDMA，Code Division Multiple Access)、全球移动通信系统(GSM，Global System for Mobile Communications)、第四代移动通信技术4G、第五代移动通信技术5G等等，多个频段包括每种制式占用的频段，例如，GSM占用的900/1800/1900MHz频段、4G占用的1920-2170MHz频段等。
基于图1所示的功率控制装置，当需要对某一种网络制式下的某一频段的输出功率信号进行处理时，采用功率控制装置1中对应的某一个功率放大支路，该功率放大支路接收该输入功率信号，并对该输入功率信号进行放大，输出功率信号。
需要说明的是，由于功率控制装置1包括多个功率放大支路，而每一个功率放大支路都包括驱动器件，则功率控制装置1包括多个驱动器件，多个驱动器件导致功率控制装置1的结构复杂，且尺寸较大，空间利用率较低。
本申请实施例提供了一种功率控制装置，如图2所示，功率控制装置2包括：控制器21、驱动器件22、可调级间匹配电路23和功率级放大电路24，控制器21和驱动器件22均分别连接可调级间匹配电路23，可调级间匹配电路23连接功率级放大电路24；可调级间匹配电路23包括多个级间匹配电路，多个级间匹配电路均连接功率级放大电路24；控制器21，用于当检测到频段选择指令时，响应于频段选择指令，从频段选择指令中确定目标频段；以及基于目标频段，从多个级间匹配电路中，确定出通路的目标级间匹配电路；驱动器件22，用于当接收到目标频段内的输入功率信号时，对输入功率信号进行预放大，得到预放大后的功率信号；可调级间匹配电路23，用于对预放大后的功率信号进行处理，得到中间输入信号，并提供给功率级放大电路；功率级放大电路24，用于对中间输入信号进行放大，得到输出功率信号。

需要说明的是，由于输入功率信号的大小有限，并且功率级放大电路的输出增益有限，为了获得一定频段内的输出功率信号，采用驱动器件对输入功率信号进行预放大。
在一些实施例中，多个级间匹配电路为工作在不同的频段的电路；多个级间匹配电路中的每个级间匹配电路向驱动器件和功率级放大电路提供一个频段所需的匹配阻抗，由每个级间匹配电路、驱动器件和功率级放大电路构成的工作通路，以最佳性能参数处理该频段内的功率信号。
需要说明的是，多个级间匹配电路共用一个驱动器件，实现对多个频段内的功率信号进行放大，如此，即通过能够提供多个频段各自所需的匹配阻抗的多个级间匹配电路，实现了扩宽频段的宽度，又通过共用一个驱动器件简化了功率控制装置的拓扑结构，实现减小功率控制装置的尺寸。

在本申请的实施例中，驱动器件22通过目标开关，连接目标级间匹配电路的一端，目标级间匹配电路的另一端连接目标功率放大器；目标级间匹配电路将驱动器件22的输出阻抗和目标功率放大器的输入阻抗都匹配到目标匹配阻抗，使得目标功率放大器获得高增益、高输出功率、好线性度和高功率附加效率(PAE，Power added efficiency)等较佳性能参数。
在一些实施例中，多个级间匹配电路中的每个级间匹配电路和多个功率放大器中的对应连接的一个功率放大器，用于实现最大效率地传输一个 频段内的功率信号。
需要说明的是，对于驱动器件和多个功率放大器中的每个功率放大器，二者各自处理任意一个频段内的功率信号时的性能参数(例如，输出功率、增益、线性度和PAE等)都受匹配阻抗的影响，所以，针对目标频段内的输入功率信号，从多个级间匹配电路中选择目标级间匹配阻抗，目标级间匹配阻抗按照目标匹配阻抗，对驱动器件和目标功率放大器进行阻抗匹配后，驱动器件和目标功率放大器以较佳的性能参数处理目标频段内的输入功率信号。

可以理解的是，从频段选择指令指中确定目标频段时，仅选择多个级间匹配电路中的目标级间匹配电路通路，进而在目标频段内的输入功率信号经过驱动器件的预放大、目标级间匹配电路的处理、及功率放大电路的放大后，得到输出功率信号，由于驱动器件仅用于对输入功率信号进行预 放大，与频段无关，也就是说，无论输入功率信号属于各个频段中的任意一个频段，都可以采用相同的驱动器件进行预放大，如此，通过各个频段共用一个驱动器件简化了功率控制装置的拓扑结构，实现提高空间利用率。

在本申请实施例中，功率控制装置接收到频段选择指令，且频段选择指令指示的目标频段对应与目标级间匹配电路连接的目标开关时，控制目标开关闭合、其他开关都断开；还控制与目标级间匹配电路对应的目标输入开关闭合，控制其他输入开关都断开；输入功率信号经过目标输入匹配电路和目标输入开关后，传输至驱动器件；驱动器件对输入功率信号进行预放大，生成预放大后的功率信号；目标级间匹配电路对驱动器件的输出阻抗和目标功率放大器的输入阻抗进行匹配，并接收预放大后的功率信号，向目标功率放大器提供中间输入信号；目标功率放大器对中间输入信号进行放大，生成输出功率信号，并传输至目标输出匹配电路；目标输出匹配电路对目标功率放大器的输出阻抗进行匹配，并将输出功率信号进行输出。
可以理解的是，功率控制装置从频段选择指令中确定目标频段时，仅选择多个级间匹配电路中的目标级间匹配电路通路，进而在目标频段内的输入功率信号经过驱动器件的预放大、目标级间匹配电路的处理、及功率放大电路的放大后，得到输出功率信号，由于驱动器件仅用于对输入功率信号进行预放大，与频段无关，也就是说，无论输入功率信号属于各个频段中的任意一个频段，都可以采用相同的驱动器件进行预放大，如此，通过各个频段共用一个驱动器件简化了功率控制装置的拓扑结构，实现提高 空间利用率。

工业实用性
本申请实施例中，由于驱动器件仅用于对输入功率信号进行预放大，与频段无关，因此，无论输入功率信号属于各个频段中的任意一个频段，都可以采用相同的驱动器件进行预放大，如此，通过各个频段共用一个驱动器件简化了功率控制装置的拓扑结构，实现提高空间利用率。
