In this paper, a design of an unequal split Wilkinson power divider (WPD), with high power split ratio, using non-uniform transmission lines (NTLs) is presented. The design is based on using NTLs in each branch of the divider instead of the conventional uniform ones. Besides the achievement of high power split ratio, the size of the designed WPD is reduced. The design procedure is presented for...

A four-way power divider/power combiner using substrate integrated waveguide (SIW) and microstrip lines is proposed and investigated. The proposed power divider consists of a double-layer substrate with a bottom layer including an SIW T-junction and a top layer including a microstrip network. This microstrip network consists of a modified Gysel power divider which provides a high isolation betw...

This paper presents a monolithically integrated broadband lumped-element Wilkinson power divider centered at 20 GHz, which was designed and fabricated to uniformly distribute power to arrays of Josephson junctions (JJs) for superconducting voltage standards. This solution achieves a fourfold decrease in chip area, and a twofold increase in bandwidth (BW) when compared to the previous narrowband...

5G new spectrum radio access should support data rates exceeding 10Gbps in most of its applications. An Ultra Wide Band (UWB) Ultra-high data rate Wilkinson power divider up to 6.9Gbps for 5G new spectrum and CAR applications is presented in this paper. The step by step design procedure, optimization and implementation of this Wilkinson power divider in 20–30GHz are completely done to achieve t...

This paper presents dual-band equal/unequal Wilkinson power dividers based on a coupled-line section with short-circuited stub (called as the “coupled-line section” for short), which consists of a pair of parallel coupled lines and a short-circuited stub. With the analyses of the phase shift and equivalent characteristic impedance, the coupled-line section is used to replace the quarter-wavelen...

A unequal Wilkinson power divider based on asymmetrical coupled line section is presented in this paper. The proposed unequal Wilkinson power divider topology uses asymmetrical coupled-line section and two transmission-line transformers. For simplification, a section asymmetrical coupled line is applied to obtain front compact matching structure. For generalization, three ports terminated imped...

In this paper, the design of equal-split quad-band Wilkinson power divider is presented. The design consists of two quad-band transmission line transformers and four isolation resistors. Standard transmission line theory and even/odd modes analyses are used to obtain closed form expressions that are solved using particle swarm optimization technique to find the required divider parameters (leng...

This work proposes a substrate integrated waveguide (SIW) power divider employing the Wilkinson configuration for improving the isolation performance of conventional T-junction SIW power dividers. Measurement results at 15GHz show that the isolation (S23, S32) between output ports is about 17 dB and the output return losses (S22, S33) are about 14.5 dB, respectively. The Wilkinson-type performa...

-A lumped element 180 Wilkinson divider consisting of 11 elements was presented in 2003. It used a conventional Wilkinson divider, a -90 and a +90 phase shifter of πand T-type. In this paper, that of 10 elements is newly presented. Frequency characteristics of the two 180 Wilkinson dividers and those of a rat-race divider known as an out of phase circuit are discussed. Key-Words: Wilkinson divi...
