摘要
A high-performance surface-acoustic-wave (SAW) filter for use in mobile telephones is presented. The design for the actual realization of the filter is examined, from the filter configuration to the final device operation. A low-loss weighting technique in an interdigital transducer, a resonant structure, computer simulation procedures, and material properties are treated. Experimental results with this SAW filter included an 830-MHz center frequency, 3% bandwidth, insertion loss as low as 3. 5 4. 0 dB, and 50-dB sidelobe suppression filter.
