Abstract : The physics of SAW bandpass filters will be reviewed emphasizing those aspects which directly impact filter performance. Next, some of the design trade-offs in these filters will be discussed including insertion loss versus fractional bandwidth, skirt steepness versus device size and cost, and the characteristics of various substrates which are commonly used. Examples of various filters will be given including filters for television IF, satellite receivers, and data communications systems. Generalized performance curves achievable with SAW bandpass filters will be presented. Projections of future developments including SAW resonator bandpass filters and single-phase unidirectional transducer filters will be discussed. (Author)
