摘要

本文提出了一种基于商用现货元件的耐辐射整n锁相环合成器。该电路的调谐范围为2.24 GHz至2.45 GHz，在1 kHz偏移时相位噪声为- 82 dBc/Hz。采用高能混合场辐射进行系统级辐照试验。第一次测试表明，该电路具有良好的长期稳定性，在8E+11cm 2的1mev等效影响下没有明显的退化。

Circuit design for a radiation tolerant 2.4 GHz synthesizer based on COTS components

This paper presents a radiation tolerant integer-N phase-locked loop synthesizer based on commercial off-the-shelf components. The circuit features a tuning range from 2.24 GHz to 2.45 GHz and a phase noise of −82 dBc/Hz at 1 kHz offset. System level irradiation testing is conducted using high energy mixed-field radiation. First tests show excellent long-term stability of the circuit with no significant degradation up to an 1 MeV equivalent fluence of 8E+11cm⁁-2.
