摘要

本文报道了一种具有可调陷波带的紧凑型宽带带通滤波器的理论设计。提出了一种十字形耦合谐振腔（CHCR），并利用ABCD矩阵分析方法对其谐振模式进行了表征。此外，通过适当调整微带电长度可以获得独立可控的通带特性。对于可调谐应用，采用变容二极管作为调谐元件，可实现8.5-10.0 GHz的陷波频率范围，调谐率为16.2%。为了演示，设计、制作和测量了可调谐电路。仿真结果与实测结果吻合良好。测量结果与理论预测吻合良好，具有可调的陷波带、高选择性、体积小、低插入损耗和理想的陷波带抑制水平等优点。

High-selectivity wideband bandpass filter with tunable notched band

In this paper, the theoretical design of a compact wideband bandpass filter (BPF) with a tunable notched band is reported. We proposed a cross-shaped coupling resonator (CHCR) which resonant modes are demonstrated by employing the ABCD matrix analysis method. In addition, the independent and controllable passband characteristics can be obtained by properly adjusting the microstrip electrical length. For tunable application, the varactor diode is employed as the tuning element to achieve a notched frequency range of 8.5–10.0 GHz and the tuning rate is 16.2 %. For demonstration, the tunable circuits are designed, fabricated and measured. Simulated and measured results are matched well. The measured results agree well with theoretical predictions, which exhibit superior performance such as tunable notched band, high-selectivity, compact size, low insertion loss (IL) and ideal notched band suppression levels.

期刊介绍： Published since 1969, the Microelectronics Journal is an international forum for the dissemination of research and applications of microelectronic systems, circuits, and emerging technologies. Papers published in the Microelectronics Journal have undergone peer review to ensure originality, relevance, and timeliness. The journal thus provides a worldwide, regular, and comprehensive update on microelectronic circuits and systems. The Microelectronics Journal invites papers describing significant research and applications in all of the areas listed below. Comprehensive review/survey papers covering recent developments will also be considered. The Microelectronics Journal covers circuits and systems. This topic includes but is not limited to: Analog, digital, mixed, and RF circuits and related design methodologies; Logic, architectural, and system level synthesis; Testing, design for testability, built-in self-test; Area, power, and thermal analysis and design; Mixed-domain simulation and design; Embedded systems; Non-von Neumann computing and related technologies and circuits; Design and test of high complexity systems integration; SoC, NoC, SIP, and NIP design and test; 3-D integration design and analysis; Emerging device technologies and circuits, such as FinFETs, SETs, spintronics, SFQ, MTJ, etc. Application aspects such as signal and image processing including circuits for cryptography, sensors, and actuators including sensor networks, reliability and quality issues, and economic models are also welcome.
