A novel general design method, which is based on S-parameters and suitable for MMIC and MEMS, has been developed for antiphase balanced oscillators in this paper. To demostrate the design method, a new type of interconnecting network is selected and a 7.0GHz balanced oscillator with antiphase dual outputs has been designed, fabricated and measured. A difference of 180 degree between two outputs has been obtained. The measured results clearly verify the proposed design method.
