In this paper, a novel I/O stage coupling scheme is presented for exploration of a triple-mode bandpass filter with improved out-of-band performance. A triple-mode stub-loaded resonator is first formed by tap-connecting a λ/2 resonator with a pair of open-ended stubs of less than λ/4 in length at it...
