In this paper, a planar three-way power divider with compact size is presented using quarter-wave long five-conductor couple line. It is analytically proved that the proposed structure allows the performance of three-way power dividers. Based on the derived equations and simulation, the three-way power divider is designed and measured at 2.0GHz. The measurement shows excellent performance with ...

When quadrature couplers and power dividers are implemented in integrated circuits, accurate isolation networks can not be realized due to the nonideal resistors process variations. We present an network design technique which cancels resistor parasitic effects also increases tolerance variations resistance values. A Lange coupler a divider designed at Ka-band using proposed process-tolerant ne...

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 seven ports network is proposed to act as a six-way power divider/combiner. The proposed network structure consists of a set of λ/4 planar transmission lines at the design frequency and does not require any isolating resistor. The power divider is capable of providing various power ratios by judicious choice of the transmission lines characteristic impedances. Design equations are derived for...

A broad-band power divider is presented in CMOS technology. The devices are realized by postprocessing chips that are fabricated in a standard 1.2m CMOS process. Developed postprocessing includes wire bonding for ground equalization, deposition of a stress-compensation layer, and selective etching of the silicon substrate. By employing coupled coplanar transmission lines, the area of dividers i...
