Chai Jun · Shipboard Electronic Countermeasure · 2007
This paper discusses the realization plan of the frequency synthesisis source by means of the direct digital synthesis(DDS)STEL-1173 and phase-locked-loop(PLL)Q3236,recommends the matters needing attention in hardware design,and analyses the phase noise and spurious characteristics of the system,finally gives the test results of the system.
