摘要
频率源是微波通信、雷达、导航及卫星通信等电子系统中的关键组成部分，承担信号产生、时钟参考及频率校准等功能，其性能直接影响系统的信号质量与频率精度。针对频率传递系统对高稳定度本振源的应用需求，本文设计了一款工作于10 GHz的介质振荡器（Dielectric Resonator Oscillator, DRO）。该振荡器采用机械调谐结构，并基于 ANSYS HFSS 与 Keysight ADS 建立无源-有源联合仿真模型，完成了电路结构设计与性能分析。仿真结果表明，该振荡器输出功率为6.834 dBm，在100 kHz频偏处的相位噪声为-133.208 dBc/Hz，整体性能较好，初步验证了其在 10 GHz 本振源设计中的可行性。
Abstract
Frequency sources are key components in electronic systems such as microwave communications, radar, navigation, and satellite communications. They perform functions including signal generation, clock referencing, and frequency calibration, and their performance directly affects signal quality and frequency accuracy. To meet the application requirements for high-stability local oscillator sources in frequency transfer systems, this paper presents the design of a 10 GHz dielectric resonator oscillator (DRO). The oscillator adopts a mechanical tuning structure, and a passive-active co-simulation model is established based on ANSYS HFSS and Keysight ADS to complete the circuit structure design and performance analysis. Simulation results show that the oscillator achieves an output power of 6.834 dBm and a phase noise of ?133.208 dBc/Hz at a 100 kHz offset. The overall performance is satisfactory, which preliminarily verifies its feasibility for 10 GHz local oscillator design.关键词
