一种Ka波段点频锁相频率源设计

Design of a Ka-Band Point-Frequency Phase-Locked Frequency Source

针对某射频系统特殊空间小型化布局需求,采用取样锁相与倍频放大混合集成技术,研制Ka波段点频源。介绍利用ADF4016频率合成器、压控振荡器、MSP430单片机等设计方案研制X波段点频锁相源,再通过倍频、放大、滤波等链路方案实现Ka波段点频源。测试结果表明,Ka波段点频源工作频率、相位噪声、输出功率等技术指标同设计相吻合。

In view of miniaturization layout demand of the radio frequency system in some special space,we implement a Ka-band point-frequency phase-locked frequency source,by a hybrid integrated technology of combining sampling phase-locked and frequency multiplier-amplifier.This paper introduces the designed schemes of the use of ADF4016 frequency synthesizer,voltage-controlled oscillator,MSP430 multi-service processors and so on to develop X-band point-frequency phase-locked sources,and then realizes the research purpose of Ka-band point-frequency sources through the link schemes including the frequency multiplier,amplifier,filter and so on.The measurement result of the Ka-band point-frequency phase-locked frequency source shows that the technical specifications of Ka-band point-frequency source operating frequency,phase noise,and output power agree well with the design.
