A Widely Tunable Compact Bandpass Filter Based on a Switched Varactor-Tuned Resonator
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 the limited tunability of varactor diodes by switching the stub...
