The design of a novel tunable filter


A novel tunable RF bandpass filter with a broad tuning range is presented. This tunable filter is realized by hairpin resonators, BaSrTiO3 (BST) films and MEMS switches. In the proposed design approach, MEMS switches and BST films are combined to achieve a larger tuning range of the central frequency. It is shown that the central frequency of the proposed… (More)
