摘　　要：将YIG振荡电路与控制单元、锁相单元进行混合集成制作频率合成器。首先介绍了YIG频率合成器的基本原理,在此基础上提出了混合集成的设计思路和具体设计措施。重点提出采用“永磁偏置”和“无加热器”方案降低体积和功耗,采用“均磁”措施提升磁场均匀性,采用YIG小球与永磁体互补法降低频率温漂,实现了YIG频率合成器的小型化和低功耗设计。其体积较常规YIG频率合成器减小约2/3,功耗仅约3.6 W,相位噪声性能与常规YIG频率合成器相当。最后指出了这种混合集成一体化结构设计的适用性,即混合集成一体化结构设计思想不仅适用于YIG频率合成器,也适用于多功能YIG滤波组件的集成化设计,但也存在不足和局限性。A hybrid-integrated frequency synthesizer which consists of YIG-tuned oscillator,control and PLL units was implemented.The basic principles of the YIG frequency synthesizer were illustrated,and then the overall design ideas and the detailed measures of hybrid-integration were proposed."Permanent magnet bias"and"no heater"schemes were adopted to reduce the volume and power consumption,"magnetic equalization"measure was adopted to improve the magnetic field uniformity,YIG sphere and permanent magnet complementary method was used to reduce the frequency temperature drift,and then a miniaturized YIG phase-locked frequency synthesizer with low power consumption was realized.Compared to conventional YIG frequency synthesizers,the volume was reduced by about 2/3,and the power consumption was only about 3.6 W.The phase noise performance was comparable to that of conventional YIG frequency synthesizers.The applicability of the hybrid-integration structure design was pointed out at the end of this paper,which was to say,the concept of the hybrid-integration structure design was suitable for not only YIG frequency synthesizers but also multi-functional YIG filtering components,but there were also shortcomings and limitations.
