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。
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.
二次变频的本振信号由PLL的输出信号经整数分频得到。
The second local frequency signal is provided by an integer-divider after PLL output.
偶次分谐波混频可有效地抑制载波泄漏、二次混频失真及本振噪声，是提高调制器精确度及直接解调器动态范围的有效技术。
In this paper, we discuss even subharmonic mixing technique which can suppress carrier leakage in microwave direct modulator, or suppress IM2…
