Abstract

The parallel feedback dielectric resonator oscillator (DRO) which is applicable to satellite communications and broadcasting has been investigated. In the design of oscillator, the phase noise is important parameter. In this paper, The proposed oscillator has good phase noise level because it suppressed harmonics. Measurement show the fabricated oscillator is output power of about 9 dBm at fundamental frequency of 12.0 GHz and fundamental frequency suppression of -47.5 dBc. The phase noise level is about -110 dBc/Hz at 100 KHz offset frequency.
