专利汇可以提供Surface wave bandpass filter with non-linear fm input and output transducers and design method therefor专利检索,专利查询,专利分析的服务。并且A microwave acoustic surface wave bandpass filter comprises a piezoelectirc substrate with interdigital comb input and output transducers on the surface thereof. The spacing of the interdigital fingers of the input transducer is chosen to be a non-linear function of the distance along the transducer. Thus the input transducer is constructed to possess a non-linear frequency versus time response such that the amplitude versus frequency response thereof is the square root of the desired amplitude versus frequency response of the filter. The output transducer is constructed as a translated image of the input transducer thereby providing the matched filter thereof. The desired amplitude versus frequency characteristic of the filter is the square of the amplitude versus frequency characteristic of either of the transducers. A method for deriving the non-linear FM function that provides the desired amplitude versus frequency characteristic for the filter is disclosed.,下面是Surface wave bandpass filter with non-linear fm input and output transducers and design method therefor专利的具体信息内容。
