摘要
介绍了X波段双通道T/R组件用LTCC多层基板的电路布局,阐述了基板电路布局中重点考虑的电磁兼容性问题及其解决办法,同时给出了微波电路的输入输出匹配和接地层参数的优化设计。经优化设计的双通道T/R组件体积小、重量轻,实测得到的单通道输出功率大于5W。
A novel circuit design of multi-layer LTCC （Low Temperature Co-fire Ceramic） substrate used in X band dual-channels T/R module is presented in this paper. EMC should be first of all to be considered and some solutions to it are introduced. The optimum design for the outer matching circuit and the constitutive parameters of ground-layer is proposed. The design results in a small-size and low-weight module. The measured module＇s output power is more than 5W for a single channel.
