【摘要】 本文着重讨论了采用“双环”和“单环”方案,获得的毫米波锁相稳频源的频率短期稳定度。导出了满足环路稳定条件的关系式及算得环路的主要参数。为测量锁相稳频源的“短稳”,研制了调频噪音测量装置并给出“短稳”的测量结果。更多还原

【Abstract】 A double-loop and a single-loop version of millimeter wave phaSe-locked sources are described. Short-term frequency stability of such yersions are discussed. The expression for loop stability criteria and the loop parameters are given A FM noise measurement set-up is developed, by means of which the FM noise of the microwave phase-locked sources is measured.更多还原
