چکیده [English]

In this paper a C-band, low phase noise voltage controlled oscillator is presented based on substrate integrated waveguide (SIW) resonator. As the SIW resonator plays a great role on the noise performance of the voltage controlled oscillator, the effects of some parameters on the performance of the SIW are investigated. Considering various techniques of excitation and tuning, an SIW resonator is designed in the frequency range of 5 to 6.3 GHz. The resulting tunable resonator has a quality factor of 240 at 5.5 GHz, when simulated on RO4003 substrate. The voltage controlled oscillator can oscillate from 5.3 GHz up to 6.3 GHz. The tuning voltage for this frequency range is between 2 and 20 Volts. The oscillator phase noise is better than -112dBc/Hz at 100 KHz offset from the 5.5 GHz carrier.
