- Abstract
A microstrip open-loop resonator oscillator operating at even modes is proposed. The even mode of the ring circuit can be predicted by using a simple transmission-line model. The new oscillator has a characteristic similar to that of a push-push oscillator. In addition, in comparison with the push-push oscillator, the new oscillator with one active device can minimize the size and lower the cost. A voltage-controlled piezoelectric transducer (PET) is used to vary the resonant frequencies of the ring resonator, which in turn tunes the oscillator with a good tuning range of 4.9% at around 12.1 GHz. This tuned oscillator should have many applications in wireless systems. © 2005 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2005.
