摘要
采用锁相方法，解决了三毫米波信号源的高稳定和低相噪问题。经测试，９２．６ＧＨｚ时其相位噪声指标（傅氏频率为１ＫＨｚ时）为－７５ｄＢｃ／Ｈｚ，杂散优于－５５ｄＢｃ，输出功率大于１０ｍＷ。
The problems of high stability and low phase noise of 3mm-wave source are solved by use of PLL. It is measured that when Fourier frequency is 1kHz and offset carrier is 92. 7GHz, the phase noise of 3mm-wave PLL source is-75dBc/Hz. Spurious is lower than-55dBc and output power is higher than 10mW.
