Chunguang Li,Qiang Zhang,Qingduan Meng,Liang Sun,Jiandong Huang,Yunfei Wang,Xueqiang Zhang,Aisheng He,Hong Li,Yusheng He,Sheng Luo +10 more
TL;DR: In this article, a narrowband high-temperature superconducting (HTS) bandpass filter with a fractional bandwidth of 0.35% in the L band was proposed.
Journal ArticleDOI
A 12-Pole Narrowband Highly Selective High-Temperature Superconducting Filter for the Application in the Third-Generation Wireless Communications
Shunzhou Li,Jiandong Huang,Qingduan Meng,Liang Sun,Qiang Zhang,Fei Li,Aisheng He,Xueqiang Zhang,Chunguang Li,Hong Li,Yusheng He +10 more
TL;DR: In this paper, an ultra-selective high-temperature superconducting bandpass filter was designed and fabricated to satisfy the demands of the third-generation wireless communications, which was designed to have 12-pole quasi-elliptic response with 4.68-MHz bandwidth in the 3G communications band (a fractional bandwidth of 0.0023).
Journal ArticleDOI
A 24-pole high T-c superconducting filter for mobile communication applications
TL;DR: In this paper, a 24-pole Chebyshev HTS bandpass filter was designed at 1748 MHz center frequency with 75 MHz bandwidth, which was suitable for the GSM base station.

Journal ArticleDOI
An impedance matched phase shifter using BaSrTiO/sub 3/ thin film
Qingduan Meng,Xueqiang Zhang,Fei Li,Jiandong Huang,Xiaohong Zhu,Dongning Zheng,Bolin Cheng,Qiang Luo,Changzhi Gu,Yusheng He +9 more
TL;DR: In this paper, a distributed phase shifter with an equal ripple return loss at its operation frequency range is presented, which is based on a periodic structure and consists of a coplanar waveguide (CPW) line periodically loaded with voltage-variable barium strontium titanate (BST) interdigitated capacitors.
