The quasi-elliptic function filter with one transmissionzero has the better selectivity than the general Chebyshev filter.
带有一对传输零点的准椭圆函数滤波器相比切比雪夫型滤波器具备更好的选择性。

As this kind of microstrip hairpin filter does not require cross coupling between the non-adjacent resonators of the filter to obtain transmissionzero, the design procedure of the filter is simple.
