| description | Oscillators are basic microwave energy sources for all microwave communication systems. This paper will discuss the theory and the design of a low phase noise 10GHz parallel feedback GaAs PHEMT dielectric resonator oscillator. The coupling coefficient between the dielectric resonator and the parallel microstrip lines are represented in the form of double coil transformer, while the dielectric resonator is modeled as a parallel RLC component. The coupling gap can be adjusted to optimize the ratio of the loaded to the unloaded quality factor to give a better phase noise. An optimum low phase noise can be achieved when an insertion loss of 9.5dB is obtained. The dielectric resonator oscillator model design was simulated using Agilent ADS software, where at 10GHz exhibited an insertion loss of 8.562 dB with a phase noise of -105.283 dBc/Hz at 100 kHz frequency offset. The output power was exhibited at +15.551 dBm |
