摘要

本文提出了一种基于混合SIW腔腔谐振腔的紧凑x波段低相位噪声振荡器。该谐振器由两个矩形波导级联的圆波导组成。在谐振器中嵌入两对孔以提高q因子。由于存在不连续的金属侧壁，可以利用圆波导的基模$\mathbf{TM}_{110}$来设计振荡器的振荡频率。所制备的振荡器已被证明在9.5 GHz频率下振荡。在100khz偏置和1.67 dBm输出功率下，相位噪声小于- 112.84 dBc/Hz，性能因数(FOM)为- 202.06 dBc/Hz。

X-Band Low Phase Noise Oscillator Based on Hybrid SIW Cavity Resonator

In this paper, a compact X-band low phase noise oscillator based on a hybrid SIW cavity resonator is presented. This proposed resonator is composed of a circular waveguide cascaded by two rectangular waveguides. Two pairs of holes are embedded into the resonator to improve the Q-factor. Owing to the existence of discontinuous metal side walls, the fundamental mode $\mathbf{TM}_{110}$ of the circular waveguide can be applied to design the oscillation frequency of the oscillator. The fabricated oscillator has been demonstrated to oscillate at 9.5 GHz. The phase noise is less than −112.84 dBc/Hz at 100 kHz offset with 1.67 dBm output power, exhibiting the figure of merit (FOM) of −202.06 dBc/Hz.
