基于LTCC基板的X波段四通道T/R组件的设计

介绍了一种X波段四通道T/R组件的设计思路和实现方法。针对组件工作频率高、工作频段宽、通道数多、功能复杂、裸芯片多、重量要求严格等难点，组件采用低温共烧陶瓷设计、MCM设计、新型硅铝盒体材料设计等先进技术，成功研制出了低噪声、轻质量、功能齐全的小型化四通道T/R组件，该组件工作带宽在X波段达到2 GHz，发射功率达到+41 dBm，发射效率达到32%，接收噪声系数达到2.5～2.8 dB，移相精度达到20（RMS），整体重量为96 g。组件已实现批量化生产。

The Design of X band 4 channel T/R Module Based on LTCC Substrate

This paper introduces the design idea and the implement method of a kind of X band four channel T/R module.Such advanced technologies as LTCC, MCM and new silicon aluminum material design are adopted in the module, in view of some difficulties such as higher working frequency, broader bandwidth, complex function, more channels, more bare chips, strict weight demand and so on.The miniaturized four channel T/R module is developed successfully with low noise figure, light weight, and complete functions. The operation bandwidth can be up to 2 GHz, the transmitting power can reach up to 41 dBm,the transmitting efficiency is as high as 32%, the noise figure is 2.5~2.8 dB, the phase shift precision (RMS value) is 2°, and the whole weigh is only 96 g. The module has been in the stage of mass production.
