| Summary: | 碩士 === 國立交通大學 === 電信工程系 === 91 === Base on a derivation with the S-parameter, a new method is proposed to design push-push oscillators in the S-band and K-band. Two push-push oscillators are realized using hybrid microwave integrated circuit.
The first oscillator is designed at 1.57GHz, of which the phase noise at 100kHz offset is —102dBc/Hz. The first push-push oscillator is designed at 1.5GHz and has an output frequency at 3GHz, of which the phase noise at 100kHz offset is —96dBc/Hz. The fundamental oscillation at 1.5GHz is suppressed by -25dB through the push-push mechanism.
The second push-push oscillator is designed to have an output frequency of 18GHz. The phase noise is measured to have —93dBc/Hz at 1MHz offset. The fundamental oscillation is suppressed by —21dBc at the push-push output.
