This paper presents a novel design of a tunable tri-band bandpass filter using varactor-tuned stub-loaded resonators. The first and the third passband center frequencies of the proposed tri-band filter can be independently tuned by controlling the different values of the capacitances and different varactor diodes, whereas the second passband center… CONTINUE READING
