摘要
本文介绍一种在一个芯片上制作全制式彩色电视声表面波中频滤波器的设计方法。该设计的特点是由一个辅助又指换能器的断开或接入。分别实现ＮＴＳＣ或ＰＡＬ（ＳＥＣＡＭ）制式中频滤波器的频率特性。实验器件的芯片尺寸是８ｍｍ×２．６ｍｍ。
This paper presents a design methed of all- standard color TV IF SAW filters fabricated on a single chip. The design is characterized by breaking or connecting an auxiliary interdigital transducer.so as to realize the frequency propertie5 for NTSC standard SAW IF filters or PAL(SECAM)standard SAW IF filters respectively. The dimension of a chip in experimental device is 8mm ×2.6mm.
