Description
Summary:The problem of obtaining ultrawideband phase chaos in the decimeter band with the use of a phase-locked loop is considered. The mathematical simulation of a third-order phase-locked loop is performed with account for the real characteristics of the phase detector, the signal frequency divider in the phase-locked loop, and the voltage-controlled oscillator. This simulation allows determination of the parameters of a prototype of a phase-locked loop operating in the chaotic generation mode. Based on the obtained results and available circuit technology, a prototype of a phase-locked loop generating ultrawideband phase-chaotic oscillations with a uniform power spectrum in a frequency range from 700 to 1300 MHz is developed and tested.
