Development of low phase noise voltage controlled oscillators

V magistrskem delu sta predstavljena delovanje in razvoj napetostno krmiljenih oscilatorjev na osnovnih frekvencah delovanja 50MHz, 100MHz in 1GHz. Kot resonator za 1GHz VCO je uporabljen SAW resonator, za 50MHz in 100MHz pa kremenčev resonator, ki resonira na osnovni frekvenci pri 50MHz VCO-ju in na tretjem overtonu pri 100MHz VCO. Uporabili smo računsko, simulacijsko in eksperimentalno metodo razvoja. Razviti VCO-ji so se izkazali kot elektronske komponente, ki jih lahko uporabimo v različnih aplikacijah ali pa za nadaljnji razvoj.The master thesis presents the operation and development of voltage-controlled oscillators at the basic operating frequencies of 50MHz, 100MHz and 1GHz. A SAW resonator is used as a resonator for the 1GHz VCO, and a quartz resonator for the 50MHz and 100MHz VCOs, which resonates at the fundamental frequency of the 50MHz VCO and at the third overtone of the 100MHz VCO. We used computational, simulation and experimental methods of development. The developed VCOs have proven to be electronic components that can be used in various applications or for further development
