Abstract :
Ceramic coaxial and SAW (surface acoustic wave) resonators are renowned for their ability to generate high spectral purity signal at microwave frequency. However, ceramic and SAW based signal sources are costly and not suited for fabrication by current integrated circuit (IC) technology due to their 3-D (three-dimensional) structure. Nor are they immune to electromagnetic interference (EMI), vibration effects, microphonics, phase hits, and frequency modulation. This paper describes CSRO (ceramic and SAW replacement oscillators), which is based on novel mode-coupled stubs-tuned planar resonators that offer user-definable, cost-effective, phase hits insensitive, integrable, compact, and low cost signal source for present and later generation wireless communication systems
