The filter comprises two stubs, resonant at one-half and one-quarter of the centre frequency, respectively, and a series overlay capacitor. The filter has a performance comparable to that of a third-order elliptic function filter and has a practical bandwidth of 16-34%.en© The Institution of Engineering and Technology 2011.
