— In this project, a method of designing a series feedback split ring resonator (SRRs) oscillator with emphasize on phase noise study has been proposed. The split ring resonator oscillator is consisted of an active device of ATF-36077, a GaAs PHEMT from Agilent, an array of split ring resonator for frequency determining element and microstrip-based output matching network. Mainly, this work focused on modeling and designing an optimum performance of SRRs oscillator in emphasizing the phase noise result. The simulation of SRRs oscillator has been modeled using Agilent Advanced Design System (ADS) and CST Microwave Studio software. Three designs of SRRs have been compared for Q-factor in which a high Q-factor of 6476 has been obtained from File C of SRR design. Subsequently, based on this design, the oscillator exhibited a low phase noise of -122.0 dBc/Hz at offset frequency of 100 kHz and an output power of 7.46 dBm at the oscillating frequency of 10.05GHz.
