摘　　要：为了满足某系统倍频功放组件需求,提出了低相位噪声、低杂散、频率捷变和高频段输出的X波段跳频本振模块设计方法.首先提出了跳频本振模块的总体设计方案,然后对P波段跳频基准电路、X波段固定点频电路进行了设计,最后采用ADS软件对相位噪声、杂散等指标进行了仿真优化.仿真结果验证了该方案的可行性.Aiming at the demand of double frequency power amplifying module of a certain system, this paper presents a design of X–band frequency hopping local oscillator(LO) module with a low phase noise, low spur,frequency agility and high frequency-section output. Firstly the paper proposes a total design scheme, and then studies and designs the P-band hopping reference circuit and X-band dot frequency circuit. Finally the paper uses ADS software to simulate and optimize the phase noise and spur. The simulation result proves the feasibility of the proposed design scheme.
