- Abstract
In view on the demand on the miniaturized dual band SAW filter, the design technology on SAW filter with two ports and two pass bands is studied. By building a dual band SAW filter acoustic-electric co-simulation platform including two groups on coupled mode (COM) parameters, the performance on the filter is analyzed and optimized. A dual-passband SAW filter packaged in CSP2520 has been successfully developed. The center frequency on the filter is 1995 MHz and 2185 MHz respectively, the passband bandwidths are both 40 MHz, the insertion loss is less than 3 dB, and the isolation between passbands is greater than 30 dB. The test results are consistent with that on the simulation.
