In particular the wireless personal communication applications require generation and locking of frequencies. For this purpose the authors use a frequency synthesizer. A frequency synthesizer generates a variety of output frequencies as multiples of single reference frequency. Performance factors like phase noise, spur noise and lock time will have large impact on the performance of frequency synthesizer. It is necessary to model the performance factors that contribute noise in the frequency synthesizer. As they use x band and ku band for wireless applications a comparative study of the performance factors is made in this paper to study their effects in x band and ku band using matlab tool for simulation.
