摘要
论述一种Ka频段上变频模块设计,对模块的杂散和相位噪声性能做了分析,根据分析结果,设计出合理的变频方案。滤波器采用Ansoft Designer和HFSS软件协同仿真,薄膜工艺制作,获得足够的杂散抑制度从而实现低杂散。应用取样锁相技术合成了相位噪声极低的27 GHz本振。对波导—微带过渡结构进行仿真,并给出仿真结果。从测试结果表明,模块设计实现了低杂散和低相位噪声。
A new Ka-band Up-converter module is described in this paper.How to achieve low spurious and low phase noise performance is studied,and then the feasible scheme is designed.The filter is co-simulated by Ansoft Designer and HFSS software and is realized with thin film technique.High spurious suppression is obtained by the filter.A 27 GHz local oscillator with very low phase noise is realized by sampling phase-locked technique.The waveguide to micro-strip transition is simulated.Finally the module is tested,and the design objective is satisfied.
