Abstract
In this paper, a new design method of a tunable oscillator using a suspended-stripline resonator is presented. The negative resistance of an FET mounted on microstrip line(MSL) is combined with a high Q suspended-stripline(SSL) resonator to produce a tunable oscillator with good phase noise. The new MSL-SSL transition facilitates the easy connection between the MSL-based circuits and the SSL module. The proposed oscillator is also frequency-tunable using a tuner located on the top of the SSL housing. The measured phase noise of the implemented oscillator at 3.37 GHz is -108.03 dBc@100 kHz and -135.09 dBc@1 MHz with 50 MHz of frequency tuning.
