STUDY OF Ka-BAND PLL SYSTEM
-
摘要: 利用多環(huán)方案,研制了八毫米波鎖相源系統(tǒng)。實驗表明,34.7GHz頻率點輸出的相位噪聲指標(傅氏頻率為1kHz時)為-78dBc/Hz,雜散優(yōu)于-60dBc,輸出功率大于40mW。Abstract: An 8mm wave PLL system is designed and manufactured by use of multi-loops. It is measured that the phase noise of mm-wave PLL source is-78dBc/ Hz (Fourier frequency is 1kHz offset carrier 37.4 GHz), spurious is lower than-60 dBc, output power is higher than 40mW.
