摘要

本文研究了一种V波段超小型低相噪频率综合器

研制了L段捷变频频综、Ku波段取样锁相源、上变频组件、倍频器等四个小型化组件.为了得到较低的相位噪声和捷变频速度

本捷变频频综采用上变频-倍频方案

其中DRO PLS保证低相位噪声性能

L波段捷变频频综保证捷变频功能.该频综尺寸为100×80×30mm

相位噪声低于-86dBc/Hz(1kHz)

捷变频时间小于40μs

杂波抑制优于-60dBc.

Abstract

A miniature low phase noise synthesizer in V band has been studied in this paper.An agile synthesizer in L band、a sampling phase locked source in Ku band、an up converter module and a frequency multiplier have been developed.An up converter a multiplier's combination has been adopted to get low phase noise and fast switching speed.In this method

DRO PLS has been applied to be a local oscillator to assure low phase noise performance

and the agile synthesizer in L band has been used to assure fast agile speed.The dimension of synthesizer is 100×80×30mm

the phase noise is below -86dBc/Hz(1kHz)

the switching speed is faster than 40 μs and the spurious output is below -60dBc.
