Therefore , the subject is to study the design theory and engineering realization of the low phase-noise phase locked source in microwave band.

在这样的背景下，本课题对低相位噪声微波锁相源的设计理论和工程实践进行了研究。

To test for this scenario, rig up an external phase-locked dual-clock source with a knob that intentionally adjusts the phase relationship of the two clocks.

为了测试这个，做一个外部相位锁定的双时钟源，带有两个时钟有意调节相位关系的节点。

From chapter three to chapter five, the three key components of the system: millimeter-wave phase locked sources, multiple frequency local source, low noise amplifier are designed and tested.

第三章至第五章分别介绍了毫米波锁相源、二倍频本振源和低噪声放大器三个系统关键的单元电路的设计过程和测试结果。
