Abstract :
Ceramic/SAW (surface acoustic wave) resonators based oscillators are known for their ability to generate high spectral purity signal at microwave frequency but they are not immune to electromagnetic interference (EMI), vibration effects, microphonics, phase hits, and frequency modulation. Moreover, Ceramic/SAW resonators are costly and not suited for fabrication by current integrated circuit (IC) technology. This work is based on innovative and novel approach by using buried multi-mode-coupled planar resonators that offer user-definable, configurable, cost-effective, phase hits insensitive Ceramic/SAW replacement oscillators (CSRO). The typical measured phase noise of CSRO for frequency 2488 MHz is better than -164 dBc/Hz @ 1 MHz offset from the carrier, and is better than the commercial available Ceramic/SAW resonators based oscillators.
