【摘要】：毫米波振荡器是毫米波雷达系统中的核心组件,对其相位噪声的研究是毫米波电路研究的重要组成部分。本文从振荡器的相位噪声公式入手,详细介绍了复数品质因数(Qsc),并且根据复数品质因数理论重新对振荡器的设计进行了分析,制作了工作在不同频率性能优良的基片集成波导(SIW)振荡器。与传统的介质振荡器相比,本文设计的基于复数品质因数的SIW振荡器不仅具有优越的相噪性能,更具有平面集成方面的优势。实测数据证明,将振荡器频点设计在滤波器复数品质因数的峰值处能够得到良好的振荡器性能。另外,本文还将基于复数品质因数的振荡器理论从S波段应用拓展至Ku波段,证明了复数品质因数理论在振荡器设计中的普适性。在介绍了复数品质因数以及SIW谐振器的相关理论后,本文首先设计了工作在X波段的基于复数品质因数的矩形SIW双模振荡器,以最简单的SIW结构得到良好的振荡器性能。随后制作了引入互补开口谐振环(CSRR)基于复数品质因数的圆形双模SIW振荡器,该振荡器1MHz频偏处的相噪为-147.1dBc/Hz,其性能指标(FOM)值为-208.0dBc/Hz,优于大部分已发表的平面振荡器。最后设计了两个采用高选择性四阶SIW谐振腔基于复数品质因数的振荡器。一款是采用交叉耦合的滤波器设计振荡器,其具有谐波抑制良好,相噪性能良好等特点;另一款是工作在Ku波段性能优越的S1W振荡器,在1MHz频偏处的相位噪声为-141.3dBc/Hz,FOM值为-209.2dBc/Hz,其性能在同频段已发表平面振荡器中处于领先水平。
[Abstract]:Millimeter wave oscillator is the core component of millimeter wave radar system. The research on phase noise of millimeter wave oscillator is an important part of millimeter wave circuit research. In this paper, the complex quality factor (Qsc),) is introduced in detail from the phase noise formula of the oscillator, and the design of the oscillator is re-analyzed according to the complex quality factor theory. A substrate integrated waveguide (SIW) oscillator with good performance at different frequencies has been fabricated. Compared with the traditional dielectric oscillator, the SIW oscillator based on complex quality factor not only has superior phase noise performance, but also has the advantage of plane integration. The measured data show that the oscillator performance can be obtained by designing the oscillator frequency point at the peak value of the complex quality factor of the filter. In addition, the theory of oscillator based on complex quality factor is extended from S band to Ku band, and the universality of complex quality factor theory in oscillator design is proved. After introducing the theory of complex quality factor and SIW resonator, this paper first designs a rectangular SIW dual-mode oscillator based on complex quality factor in X-band, and obtains good performance with the simplest SIW structure. Then a circular dual-mode SIW oscillator with complementary open-loop (CSRR) based on complex quality factor is fabricated. The phase noise at the 1MHz frequency offset of the oscillator is-147.1 dBC / Hz, and the performance index (FOM) is-208.0 dBcxHz, and the frequency offset of the oscillator is-147.1dBcxHz, the performance index of the oscillator is-208.0dBcHz. Superior to most published planar oscillators. Finally, two oscillators with high selectivity fourth-order SIW resonator based on complex quality factor are designed. One is using cross-coupled filter to design oscillator, which has the characteristics of good harmonic suppression, good phase noise performance and so on. The other is the S1W oscillator with superior performance in the Ku band. The phase noise at the 1MHz frequency offset is-141.3 dBC / Hz and the FOM value is-209.2 dBC / Hz. The performance of the oscillator is in the leading position in the published planar oscillator in the same frequency band. The phase noise at the 1MHz frequency offset is-141.3 dBC / Hz and the FOM value is-209.2 dBC / Hz.
