Abstract :
In frequency hopping spread spectrum (FH-SS) communication, the ability of the frequency synthesizer is required to switch the carrier frequency quickly. But, if a conventional PLL is used as a component of the synthesizer, high speed frequency switching is not expected because of the time constant of PLL. The authors propose new type synthesizer independent on above time constant, and describe the experimental results
