Abstract: This paper presents a compact tunable bandpass filter (BPF) based on a switched varactor tuned resonator with a wide frequency-tuning range and a constant absolute bandwidth (ABW). The proposed switched varactors are adopted to overcome… read more here.

DOI: 10.1109/tmtt.2021.3098835
Abstract: This article demonstrates a 10.23–15.7-GHz varactor-tuned microstrip bandpass filter (BPF) with fully controllable center frequency, bandwidth, and transmission zeros. The concept of cascading a tunable low-pass unit together with a tunable high-pass unit is adopted… read more here.
