In this brief, a novel symmetrical broadband tight-coupled directional coupler with high
directivity using three-folded-coupled lines is proposed and implemented. The directional …

This paper presents a class of compact narrow/wide band branch-line couplers with
improved upper-stopband. Firstly, by analyzing stub-loaded transmission lines, it is found …

This paper presents the analysis and design of a hybrid lumped-element coupler in which
the loss of components is considered. First, only the loss of each capacitor is considered and …

In this paper, new 3 dB/10 dB filtering couplers using branch line loading, multi-line hybrid
coupling, and electromagnetic coupling, which are based on self-packaged suspended …

This paper presents wideband compact differential reflective phase shifter based on the
double layer slot-coupled coupler configuration. This novel phase shifter arrangement …

In this paper, a novel power amplifier (PA) is proposed. An asymmetrical branch-line coupler
is exploited as the output matching circuits of the proposed PA. Meanwhile, by setting the …

Design and development of coaxial line‐based 10–40 dB variable loop type dual‐
directional coupler for the frequency range of 50–500 MHz for 2 kW power handling …

In this study, the implicit Crank–Nicolson finite-difference time-domain (CN-FDTD) method is
applied to discretize the governing telegrapher's equations of a composite right-/left-handed …

This paper demonstrates symmetric backward wave quasi-0 dB coupled line coupler (CLC)
based on the globe shaped composite right/left-handed transmission line (GS-CRLH-TL) …

This article presents the design and fabrication of 20±0.3 dB directional coupler having 2 kW
power handling capability in the frequency range of 140–200 MHz. The developed coupler …
