It is described that the development of wideband SAW resonators and their applications to variable frequency filters and oscillators aiming at adopting highly sophisticated radio communication systems. At first, a systematic design technique was proposed for suppressing spurious responses of wideband surface acoustic wave (SAW) resonators. Then, the variable frequency band elimination filters including the SAW resonators were developed. It was shown that the filter enables us to realize an UHF variable frequency oscillators with low phase noise property. Finally, active filter in UHF range based on recursive architecture was investigated. It is also shown that the developed self-tuning techniques implemented the controller of the filter works fine.
