【摘要】：小型化高集成度是现代微波毫米波通信技术的发展趋势,而射频无源元件是制约其小型化的主要因素之一。滤波器和双工器是微波毫米波系统中的主要无源元件,其小型化具有重要意义。本文主要针对小型化高性能微波毫米波滤波器和双工器开展研究,并将之应用于改善振荡器的噪声性能。论文的主要工作如下：1.提出了一种引入传输零点的方法,设计并研制了V波段两级和四级带通滤波器。引入的两个传输零点(TZs)可由扰动槽单独控制,分别位于61.25 GHz和68.6 GHz,而其它TZs仍然位于上阻带。双腔滤波器的分数带宽为2.5%,插入损耗为1.35 dB,回波损耗小于20 dB,带外抑制约65 dB。相关研究成果已发表在Journal of Infrared and Millimeter Waves (SCI源刊)。2.提出并研制了一种毫米波高选择性高隔离度双工器。测试结果表明,插入损耗小于1.37 dB,隔离度为70 dB。相关研究成果已发表在IEEE Microwave and Wireless Components Letters (SCI源刊)。3.基于基片集成波导(SIW)技术,提出了一种产生和控制TZs的扰动方法并设计和研制了平面集成双模滤波器。采用标准的单层PCB工艺和0.254 mm厚的Rogers5880基片制作了单腔和双腔SIW带通滤波器。相关研究成果已在IEEE 2015 Asia-Pacific Microwave Conference会议上发表。4.将SIW高选择性滤波器用于改善X波段振荡器的相位噪声(PN)性能。采用双腔高选择性SIW滤波器的振荡器PN比单腔的PN从-106.2dBc/Hz@100KHz改善到了-114.1dBc/Hz@100KHz,相关研究成果已投稿至IEEE Microw. and Wireless Comp. Letters。
[Abstract]:Miniaturization and high integration are the development trend of modern microwave and millimeter wave communication technology, and RF passive components are one of the main factors restricting the miniaturization of microwave and millimeter wave communication technology. Filter and Duplexer are the main passive components in microwave millimeter wave system, and their miniaturization is of great significance. In this paper, miniaturization and high performance microwave millimeter wave filters and duplexers are studied and applied to improve the noise performance of the oscillator. The main work of this paper is as follows: 1. This paper presents a method of introducing transmission zeros and designs and develops two and four stages bandpass filters in V band. The two introduced transmission zeros (TZs) can be controlled separately by the perturbation channel at 61.25 GHz and 68.6 GHz, respectively, while the other TZs is still in the upstop band. The fractional bandwidth of the dual-cavity filter is 2.5 and the insertion loss is 1.35 dB,. The echo loss is less than 20 dB,. The out-of-band suppression is about 65 dB.. The related research results have been published in the Journal of Infrared and Millimeter Waves (SCI Source). A millimeter wave high selectivity high isolation duplex is proposed and developed. The test results show that the insertion loss is less than 1. 37 dB, and the isolation is 70 dB.. Related research results have been published in the IEEE Microwave and Wireless Components Letters (SCI Source). Based on the substrate integrated waveguide (SIW) technique, a perturbation method for generating and controlling TZs is proposed, and a planar integrated dual-mode filter is designed and developed. Standard single-layer PCB process and 0.254 mm thick Rogers5880 substrate are used to fabricate single-cavity and dual-cavity SIW bandpass filters. The related research results were presented at the IEEE 2015 Asia-Pacific Microwave Conference. 4. 4. SIW high selectivity filter is used to improve the phase noise (PN) performance of X band oscillator. The oscillator PN with double cavity high selectivity SIW filter is improved from-106.2dBc/Hz@100KHz to -114.1 dBc / Hz @ 100KHz compared with single cavity PN. The related research results have been submitted to IEEE Microw.. And Wireless Comp. Letters.
