| Abstract;This paper examines wide-band surface acoustic wave(SAW) filters on IF and RF stages, respectively. For IF stages, some design techniques to realize wide-band SAW filters using slanted finger interdigital transducers(SFITs) have been presented. For RF stages, some design methods to increase stop-band attenuation for low-loss SAW filters using interdigitated interdigital transducers(IIDTs) have been shown. A flip-chip assembly technique for RF SAW filters is also proposed. A miniature SAW filter with 2.5mm*2.0mm*0.9mm in size is realized by using this technique. (author abst.) |
