    • A variable power divider and method can vary the RF power between ports in a high power and multi-carrier RF environment, such as is used in controlling signals sent and received in a base station antenna. The variable power divider can include a single-control phase shifter and a hybrid power divider. The single-control phase shifter can comprise a three-port device having a single input port and two output ports. The single-control phase shifter can further comprise a variable adjuster that can change or adjust the phase between two RF signals. The hybrid power divider can comprise a four-port device having two input ports and two output ports. Both the single-control phase shifter and the hybrid power divider can comprise substantially planar structures that are suitable for high-speed manufacturing. The output ports of the hybrid power divider can be coupled to various devices such antennas or power absorbing elements.
    • 可变功率分配器和方法可以改变高功率和多载波RF环境中的端口之间的RF功率,例如用于控制在基站天线中发送和接收的信号。 可变功率分配器可以包括单控制移相器和混合功率分配器。 单控制移相器可以包括具有单个输入端口和两个输出端口的三端口设备。 单控制移相器还可以包括可以改变或调整两个RF信号之间的相位的可变调节器。 混合功率分配器可以包括具有两个输入端口和两个输出端口的四端口设备。 单控制移相器和混合功率分配器都可以包括适合于高速制造的基本上平面的结构。 混合功率分配器的输出端口可以耦合到各种设备,例如天线或功率吸收元件。
