| Abstract(in English) | We have developed a method for tuning the bandwidth of microstrip filter. Several π-shaped waveguides are placed between the resonators, and the bandwidth is tuned in discrete steps by changing the switch states of the waveguides, which changes the coupling coefficient between the resonators. The filter contains 3-pole half-wavelength straight-line resonators and four π-shaped waveguides for bandwidth tuning. It also has several electrical pads distributed around the feed lines for trimming after tuning. The filter achieves a measured 2.4:1 tunable passband ratio. The measurement results showed that the π-shaped waveguides are effective in tuning the bandwidth. |
