In this paper, a wideband directional coupler is proposed for high-power applications, which composed of transformer and lumped elements. The introduction the greatly improves directivity coupler. measurement results demonstrate that design has an excellent return loss (>17 dB), small insertion (<0.4 high (>22) over wide frequency band (10–350 MHz). Meanwhile, it can achieve flat coupling level...
In this paper, a miniaturized planar rat-race coupler is proposed to achieve arbitrary power division ratio and harmonic suppression performance simultaneously. It consists of six enhanced Tshaped line sections. The T-shaped lines can be equivalent to arbitrary electrical length lines rather than the conventional λ/4 lines. The explicit design formulas are derived and the characteristic impedan...
