Design of a Highly Efficient and Wideband Power Amplifier With a New Microstrip Low‐Pass Filter

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
In this letter, a highly efficient and wideband power amplifier (PA) is proposed based on resistive–resistive series of continuous modes (Res‐Res SCMS) with a new microstrip low‐pass filter (LPF). By employing a conventional real‐to‐real impedance transformer, the output and input matching networks are realized by incorporating the transistor′s ...

Dual-mode dual-band microstrip filters

2009 European Microwave Conference (EuMC), 2009
A compact dual-band microstrip bandpass filter is proposed using dual-mode resonators. Two microstrip loop resonators, one within the other, are employed to obtain dual-mode dual-band filter responses. Each loop resonator uses two loading elements to excite dual modes.

A Compact Wideband HTS Duplexer Using Dual‐Mode Resonators with Improved Isolation

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
A wideband high‐temperature superconducting (HTS) duplexer is designed and is characteristic of more than 50% fraction bandwidth in its two channels. The duplexer is composed of a linear half‐wavelength resonator and two channels. Each channel is composed of five dual‐mode resonators with the attenuated second harmonic.

Cobalt Tungstate Characterization Using Matryoshka‐Structure Filter

Advanced Engineering Materials, Volume 27, Issue 23, December 2025.
The green synthesis of cobalt tungstate (CoWO4) using natural polymerizing agents from agar–agar and commercial produces environmentally friendly materials with tunable structural and electromagnetic properties. X‐ray diffraction and Rietveld refinement correlate crystal structure with microwave transmission losses in Matryoshka‐type filters.
