单个标准模块主要由中间通孔式连接手臂、履带驱动链传动装置、模块偏转锥齿轮传动装置、模块俯仰链传动装置、连接柄等组成。
A standard such module is mainly composed of the link arm, the link handle, the track driven system, the offset pitch joint, the offset yaw joint and so on.
在一般LTCC模块内部，通孔做为一种电气连接单元，在信号频率足够高时其引入的电感会使模块性能恶化。
In a common LTCC filter, vias, an electric connecting, would act as a great inductance and worsen the performance of the model, when the operation frequency was high enough.
