| SAW Devices(SAW Filters) SAW Filters Type: EFCH D SAW Filter for Cellular Telephone which incorporates highly-precise interdigited electrodes achieves low insertion loss, high selectivity. Thus the filter has wide applications to bandpass filtering circuits for cellular telephones and portable wireless equipment. Stable against severe conditions of vibration and shock thanks to the unique monolithic construction of the filter Low insertion loss and excellent selectivity Contributes to circuit simplification and adjustment free Saves the hight on PC board Features Recommended Applications The RF-stage band pass filter for cellular telephone or portable wireless equipment Explanation of Part Numbers 1 2 3 4 5 6 7 8 9 10 11 12 E F C H 8 8 1 M T D A Design No. Product Code Filters EFC H Type SAW Nominal Center Frequency 836 MHz 836 M 881 MHz 881 M 897 MHz 897 M 942 MHz 942 M 1575 MHz 1575 1740 MHz 1740 1747 MHz 1747 1842 MHz 1842 1880 MHz 1880 1950 MHz 1950 1960 MHz 1960 2140 MHz 2140 8894 1819 8819 9418 881 MHz / 942 MHz (Dual) 1842 MHz / 1960 MHz (Dual) 881 MHz / 1960 MHz (Dual) 942 MHz / 1842 MHz (Dual) T Material LiTa03 DJ DK DL DA DB DE DF 1.8 1.8 1.8 1.4 1.4 1.4 1.4 Package 1.4 mm Dual Filter 1.4 mm Dual Filter 1.4 mm Dual Filter 1.1 mm Single Filter 1.1 mm Single Filter 1.1 mm Single Filter 1.1 mm Single Filter Design and specifications are each subject to change without notice.
