【摘要】 本文提出了一个微发频率合成器的设计方案。该方案用低频数字锁相环实现波道变换,用脉冲锁相环将频率倍频到微波波段。文中着重阐述了该合成器的主要部件——100兆赫模拟数字混合锁相环和1000兆赫脉冲锁相环的设计原理。更多还原

【Abstract】 A microwave frequency synthesizer design, in which a low frequency digital phase locked loop is used to realize band transformation and a pulse phase-locked loop to multiply the frequency to microwave band is presented. The main components of the synthesizer, the 100 MHz A/D mixed phase-locked loop and the 1000 MHz pulse phase-locked loop are described in detail.更多还原
