摘要
A new bandstop filter is presented providing a two-state discrete wide tuning range from 20 to 30 GHz with the same high rejection level of 36 dB. In the design, metal-insulator-metal capacitors are placed on one end of the resonators and on the other end capacitive micro-electromechanical systems (MEMS) switches are used to discretely tune the centre reject band of the filter.
