摘要
介绍声表面波锥形叉指换能器的基本原理,采用折线电极锥形叉指换能器制作的TD-SCDMA制式用96MHz宽带滤波器,1dB带宽4.8MHz,15dB抑制小于6.4MHz,插入衰耗约12dB,封装为SMD(13.3mm×6.5mm)。
The basic properties of SAW tapered IDT is presented. The 96 MHz wideband SAW filter for TD-SCDMA using tapered IDT with broken line electrodes achieves a minimum insertion loss of 12 dB, 1 dB pass band of 4.8 MHz, and 15 dB rejection stop band smaller than 6.4 MHz, and is packged in SMD（13.3 mm×6.5 mm）.
