Broadband multilayer active-slot power divider

Abstract

A novel multilayer broadband active-slot power divider is proposed for the first time. As compared to the conventional active multilayer power divider [7], whose 3-dB bandwidth of small-signal gain is typically about 40%, the overall 3-dB bandwidth of the small-signal gain of the proposed multilayer active-slot power divider is about 52%. Through the modification of the T-junction, the proposed power divider is able to provide the characteristics of balance, low loss, and broad band. The proposed device can also provide the possibility of uneven power outputs under appropriate load modifications and amplifications. © 2004 Wiley Periodicals, Inc.
