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.
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.
