Tunable Bandpass Filter Using a Switched Tunable Diplexer Technique
IEEE Transactions on Industrial Electronics, 2017In this paper, a new technique using two p-i-n diodes to switch between two channels of a tunable diplexer with constant return loss is proposed to design a tunable bandpass filter (BPF) with wide frequency tuning range (FTR). The used third-order tunable diplexer with two independently tuned channels consists of one common varactor-tuned lumped ...

A Compact and Low-Loss Tunable Bandpass Filter Using YIG/GGG Film Structures
IEEE Microwave and Wireless Technology Letters, 2023A compact and low-loss magnetically tunable bandpass filter (BPF) is presented in this letter. The yttrium iron garnet/gadolinium gallium garnet (YIG/GGG) film structure is regarded as a resonator excited by a stepped terminal short-circuited stripline ...

Swarm Intelligence-Homotopy Hybrid Optimization-Based ANN Model for Tunable Bandpass Filter
IEEE transactions on microwave theory and techniques, 2023High-performance tunable radio frequency (RF)/ microwave and millimeter-wave filter design is a challenging task due to the lack of a basic theory. The filtering characteristics are highly sensitive to the variation of tuning elements that are commonly ...
