摘要:

提出了一种基于LTCC陶瓷基板的自封焊小型化光电探测模块,通过LTCC内埋电阻发热快速实现器件的密封。该模块不仅可以支持内部集成多种功能的光电芯片,还可与外部单元实现平面化、表贴式贴装,大幅提升模块安装适配性与可靠性。通过测试,模块在18GHz频率范围内具有高响应度与高平坦度,在体积上相较分立器件缩小了一个数量级,同时模块成本预计可降低一半以上,在机载、星载、弹载等平台的宽带相控阵系统中具有广阔的应用前景。

Abstract:

In this study, we developed a self-sealing miniaturized photoelectric detection module based on a low-temperature co-fired ceramic (LTCC) substrate. We confirmed that the module facilitates the rapid sealing of devices through the heating of the embedded resistance of the LTCC. It supports the internal integration of multi-functional optoelectronic chips and enabled planar and surface-mount mounting with external units; therefore, the module exhibits enhanced installation adaptability and reliability. Test results showed that the module has high responsiveness and flatness in the 18GHz frequency range, with its volume reduced by an order of magnitude compared to that of a discrete device. The cost of the module is expected to decrease by more than half, making it suitable for a wide range of applications in broadband phased array systems on airborne, spaceborne, missile-borne, and other platforms.
