摘要

|提出了一种高度封装的耦合器，采用垂直放置的电感和电容器(LC)元件，用于1和1.5特斯拉(T)磁共振成像(MRI)应用。该耦合器采用24层低温共(cid:12)红色陶瓷(LTCC)衬底，通过在垂直尺寸上堆积lc元件实现完全集成。该耦合器的最小报告尺寸仅为0.0035 (cid:2) 0.0021 (cid:2) 0.00001 (cid:21)g和44%的宽分数带宽(FBW)。耦合和通过端口之间的测量带内相位差和幅度不平衡分别小于91◦(cid:6) 0: 5◦和0.75 dB。还进行了比较和讨论。

Highly Packaged LTCC Coupler Using Vertically Stacked LC-elements for 1 and 1.5 Tesla MRI Applications

|A highly packaged coupler using vertically placed inductors and capacitors (LC)-elements is proposed for 1 and 1.5 Tesla (T) magnetic resonance imaging (MRI) applications. The coupler is made on a 24-layer thickness low temperature co-(cid:12)red ceramic (LTCC) substrate, and the full integration is reached by heaping up LC-elements in the vertical dimension. The coupler has a smallest reported size of only 0 : 0035 (cid:2) 0 : 0021 (cid:2) 0 : 001 (cid:21)g and a wide fractional bandwidth (FBW) of 44%. The measured in-band phase diﬀerence between the coupled and through ports and the amplitude imbalance are less than 91 ◦ (cid:6) 0 : 5 ◦ and 0.75 dB, respectively. Comparisons and discussions are also implemented.
