reference divider造句

the mm-wave section contains quadruple multiplication stage and iq modulation part . measurement has testified that triple-tuning of dds frequency 、 reference divider ratio 、 and loop divider ratio avoided frequencies with high spur level while ensuring the realization of total frequencies . the spur level is below-55dbc and frequency resolution reached 100khz; dds output frequency was up-converted to drive the m / n pll, reducing phase noise, which is better than-87dbc / hz @ 1khz,-92dbc / hz @ 10khz, decreasing frequency-hopping time which is less than 14us
系统分为微波与毫米波两大部分,微波部分综合利用了dds、lo混频锁相环和rf混频锁相环实现两路频差15mhz的xband全相参信号;毫米波部分,将xband本振信号四倍频得到毫米波本振;xband载波信号经开关控制形成脉冲信号,倍频、iq调制后得到毫米波发射信号。
