摘要
在低温共烧陶瓷(LTCC)衬底上设计并测量了频率范围为10 GHz至25 GHz的贴片式平衡器。为了降低多层耦合器中错位的影响，提出了一种对错位不敏感的多层耦合器结构。该封装在接平面上有用于SMT的端口，在电路顶部有一个保护罩来保护电路。每条传输线都被模拟成一条嵌入式微带线，以考虑覆盖效应。所有的内部端口都通过过渡连接到地平面的输出端口。包括覆盖层在内，LTCC总层数为5层。外形尺寸小至5.5 mm /spl倍/ 5.5 mm /spl倍/ 0.5 mm。
A K-band LTCC SMD type balun using a multi-layer coupler insensitive to misalignment
An SMD type balun with a frequency range from 10 GHz to 25 GHz in a low temperature co-fired ceramic (LTCC) substrate is designed and measured. To reduce the effect of misalignment in the multilayer coupler, we propose a novel multilayer coupler structure which is insensitive to misalignment. The package has ports on the ground plane for the SMT, and a cover on top of the circuit to protect the circuit. Every transmission line is simulated as an embedded micro-strip line to account for the cover effect. All the internal ports are connected to the output ports at ground plane through via transition. The total number of LTCC layers is 5 including the cover layer. The overall dimension is as small as 5.5 mm /spl times/ 5.5 mm /spl times/ 0.5 mm.
