A Research of Fast Frequency Hopping Synthesizers based on PLL
Wenge Yang · Fire Control and Command Control · 2008
The developing situation of Frequency hopping communication technical and its main technique are briefly introduced.Based on that,the main research content of frequency hopping synthesizers is brought forward.Then we briefly explain the basic theory of Phase Locked Loop(PLL) and the basic characteristic of its components.Following that,from the phase point of view,we analysis the loop model of PLL and the phase transfer function;we also deduce the connection between the loop bandwidth and other parameters.At last,we taking the ADF4193 as an example explain the realization method of Fast Frequency Hopping Synthesizers in details,and the test results is given out.
