对甚高频 ( UHF)高性能 SAW滤波器干扰模式采用了一种新的处理方法 ,即采用梯形 SAW单元网络与微带组合电路构成 SAW滤波器 ,用微带电路对干扰模式进行抑制。设计过程简洁 ,可采用成熟的 SAW单元电极和叉指参数进行计算机模拟 ,且当所设计的滤波器通带频率和带宽变化时 ,参数调整方便。并成功地用于 914MHz,带宽 17MHz滤波器的设计。 A new approach to the UHF high performance SAW filter interference mode is to use a combination of a trapezoidal SAW cell network and a microstrip combination to form a SAW filter and suppress the interference mode with a microstrip circuit. The design process is simple and can be simulated by the mature SAW electrode and interdigital parameters. And when the designed passband frequency and bandwidth of the filter are changed, the parameter adjustment is convenient. And successfully used for 914MHz, bandwidth 17MHz filter design.
