Abstract

. A compact lumped-element balun is proposed for 128 MHz frequency 3 Tesla (T) magnetic resonance imaging (MRI) applications. The proposed L-C embraced structure places vertically-interdigital-capacitor (VIC) inside spiral inductor, thus three L-C elements only take up one inductor’s area. Therefore, significant size reduction and integration increment are both achieved without increasing the number of substrate layers. The balun is built on a 10-layer thickness low temperature co-fired ceramic (LTCC) substrate and has the smallest reported size of only 0.007 × 0.008 × 0.0009 λ g . Moreover, the proposed balun also has a 2 nd -order harmonic suppression of 32 dB. Fur-thermore, comparisons and discussions are also implemented.

紧凑型LTCC Balun采用L-C拥抱结构，用于128 MHz 3T MRI应用

提出了一种用于128MHz频率3特斯拉（T）磁共振成像（MRI）应用的紧凑集总元件巴伦。所提出的L-C包围结构将垂直叉指电容器（VIC）放置在螺旋电感器内，因此三个L-C元件只占用一个电感器的面积。因此，在不增加衬底层的数量的情况下，可以实现显著的尺寸减小和集成度增加。巴伦是建立在一个10层厚的低温共烧陶瓷（LTCC）衬底上的，最小的报告尺寸仅为0.007×0.008×0.0009λg。此外，所提出的巴伦还具有32dB的二阶谐波抑制。此外，还进行了比较和讨论。

期刊介绍： Since 1992, the Radioengineering Journal has been publishing original scientific and engineering papers from the area of wireless communication and application of wireless technologies. The submitted papers are expected to deal with electromagnetics (antennas, propagation, microwaves), signals, circuits, optics and related fields. Each issue of the Radioengineering Journal is started by a feature article. Feature articles are organized by members of the Editorial Board to present the latest development in the selected areas of radio engineering. The Radioengineering Journal makes a maximum effort to publish submitted papers as quickly as possible. The first round of reviews should be completed within two months. Then, authors are expected to improve their manuscript within one month. If substantial changes are recommended and further reviews are requested by the reviewers, the publication time is prolonged.
