Abstract :
The authors present the results of a feasibility study of the monolithic integration of an FM upconversion receiver. The on-chip selectivity is obtained with silicon-integrated surface acoustic wave (SAW) filters using a ZnO-SiO2-Si layered structure. The modeling of SAW devices for optimum signal transfer, essentially from the usual power matching approach, is presented. Using the equivalent circuit model, it is concluded that the SAW filter should be driven by a balanced voltage and loaded with a differential short circuit. The integration of SAW filters and electronic circuitry is realized in the 3-GHz BiFET process. Measurements on silicon-integrated SAW devices and electronic circuitry are presented
