阅读说明：本技术 具有陷波滤波器的滤波器电路 (Filter circuit with notch filter ) 是由 R·海贾纳 于 2019-01-28 设计创作，主要内容包括：一种滤波器电路,在信号线中包括：带滤波器(BF),允许让有用频带通过；以及陷波滤波器(NF),串联地电路连接到带滤波器以滤除阻带频率。陷波滤波器包括多个并联分流元件(SE1…SE6)的串联电路,其中每个分流元件的频率相对于其他分流元件的频率发生偏移,分流元件的频率被分布(f1…F6)在陷波带上。所有分流元件可以被实现为包括具有不同间距的区域的SAW单端口谐振器(TR<Sub>NF</Sub>)。(A filter circuit comprising, in a signal line: a Band Filter (BF) allowing the useful frequency band to pass; and a Notch Filter (NF) electrically connected in series to the band filter to filter out the stop band frequency. The notch filter comprises a series circuit of a plurality of shunt elements (SE1 … SE6) connected in parallel, wherein the frequency of each shunt element is shifted with respect to the frequency of the other shunt elements, the frequency of the shunt elements being distributed (F1 … F6) over a notch band. All shunt elements can be implementedNow a SAW single-port resonator (TR) comprising regions with different pitches NF )。)
