在Sierra最近发表的文章中,提出了一个对称常值电阻点阵,以此作为无源脉冲压缩滤波器(图1)。四阶逼近式使得在四个点阵臂的每一个中,都有四个无功元件。滤波器的元件值必须严格地对称,以得最佳之效果。
In a recently published article in Sierra, a symmetrical constant-value resistive lattice was proposed as a passive pulse compression filter (Figure 1). The fourth-order approximation allows four reactive elements in each of the four lattice arms. Filter element values must be strictly symmetrical for best results.
