The Design and Implementation of PLDRO(Phase Locked Dielectric Resonator Oscillator) Using Dual Phase Lock Loop Structure
Abstract
In this work, A PLDRO (Phase Locked Dielectric Resonator Oscillator) which can be used for the wireless communication systems fur MMC(Microwave Micro Cell) and ITS wireless communication system is designed. A different approach to the PLDRO structure is applied for phase locking by dual phase lock loop structure. The proposed dual loop PLDRO generates the output power of 0 dBm at 18.7 GHz and has the characteristics of a phase noise of -80 dBc/Hz at 1kHz, -83 dBc/Hz at 10 kHz offset frequency from carrier frequency
